Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2016-05-04

This series contains updates to ixgbe, ixgbevf and traffic class helpers.

Sridhar adds helper functions to the tc_mirred header to access tcf_mirred
information and then implements them for ixgbe to enable redirection to
a SRIOV VF or an offloaded MACVLAN device queue via tc 'mirred' action.

Amritha adds support to set filters with multiple header fields (L3,L4)
to match on.

KY Srinivasan from Microsoft add Hyper-V support into ixgbevf.

Emil adds 82599 sub-device IDs that were missing from the list of parts
that support WoL.  Then simplified the logic we use to determine WoL
support by reading the EEPROM bits for MACs X540 and newer.

Preethi cleaned up duplicate and unused device IDs.  Fixed our ethtool
stat reporting where we were ignoring higher 32 bits of stats registers,
so fill out 64 bit stat values into two 32 bit words.

Babu Moger from Oracle improves VF performance issues on SPARC.

Alex Duyck cleans up some of the Hyper-V implementation from KY so that
we can just use function pointers instead of having to identify if a
given VF is running on a Linux or Windows PF.

Usha makes sure that DCB and FCoE is disabled for X550EM_x/a MACs and
cleans up the DCB initialization in the process.

Tony cleans up the API for ixgbevf_update_xcast_mode() so we do not
have to pass in the netdev parameter, since it was never used in the
function.

The multicast/all-multicast internal flags are not properly restored

Michael Chan 67a95e2022 bnxt_en: Need memory barrier when processing the completion ring.
The code determines if the next ring entry is valid before proceeding
further to read the rest of the entry.  The CPU can re-order and read
the rest of the entry first, possibly reading a stale entry, if DMA
of a new entry happens right after reading it.  This issue can be
readily seen on a ppc64 system, causing it to crash.

Florian Westphal 9b36627ace net: remove dev->trans_start
previous patches removed all direct accesses to dev->trans_start,
so change the netif_trans_update helper to update trans_start of
netdev queue 0 instead and then remove trans_start from struct net_device.

AFAICS a lot of the netif_trans_update() invocations are now useless
because they occur in ndo_start_xmit and driver doesn't set LLTX
(i.e. stack already took care of the update).

As I can't test any of them it seems better to just leave them alone.

Florian Westphal 4d0e965732 drivers: replace dev->trans_start accesses with dev_trans_start
a trans_start struct member exists twice:
- in struct net_device (legacy)
- in struct netdev_queue

Instead of open-coding dev->trans_start usage to obtain the current
trans_start value, use dev_trans_start() instead.

This is not exactly the same, as dev_trans_start also considers
the trans_start values of the netdev queues owned by the device
and provides the most recent one.

For legacy devices this doesn't matter as dev_trans_start can cope
with netdev trans_start values of 0 (they are ignored).

This is a prerequisite to eventual removal of dev->trans_start.

In the receive path a queue's work bit was cleared unconditionally even
if fec_enet_rx_queue only read out a part of the available packets from
the hardware. This resulted in not reading any packets in the next napi
turn and so packets were delayed or lost.

Emmanuel Grumbach 5c08b0f502 iwlwifi: mvm: don't override the rate with the AMSDU len
The TSO code creates A-MSDUs from a single large send. Each
A-MSDU is an skb and skb->len doesn't include the number of
bytes which need to be added for the headers being added
(subframe header, TCP header, IP header, SNAP, padding).

To be able to set the right value in the Tx command, we
put the number of bytes added by those headers in
driver_data in iwl_mvm_tx_tso and use this value in
iwl_mvm_set_tx_cmd.

The problem by setting this value in driver_data is that
it overrides the ieee80211_tx_info. The bug manifested
itself when we send P2P related frames in CCK since the
rate in ieee80211_tx_info is zero-ed. This of course is
a violation of the P2P specification.

To fix this, copy the original ieee80211_tx_info to the
stack and pass it to the functions which need it.
Assign the number of bytes added by the headers to the
driver_data inside the skb itself.

This patch assumes that the bnxt hardware will ignore existing IPv4/v6
header fields for length and checksum as well as the length and checksum
fields for outer UDP and GRE headers.

I have been told by Michael Chan that this is working.  Though this might
be somewhat redundant for IPv6 as they are forcing the checksum to be
computed for all IPv6 frames that are offloaded.  A follow-up patch may be
necessary in order to fix this as it is essentially mangling the outer IPv6
headers to add a checksum where none was requested.

>From what I can tell the ConnectX-3 will support an inner IPv6 checksum and
segmentation offload, however it cannot support outer IPv6 headers.  This
assumption is based on the fact that I could see the checksum being
offloaded for inner header on IPv4 tunnels, but not on IPv6 tunnels.

For this reason I am adding the feature to the hw_enc_features and adding
an extra check to the features_check call that will disable GSO and
checksum offload in the case that the encapsulated frame has an outer IP
version of that is not 4.  The check in mlx4_en_features_check could be
removed if at some point in the future a fix is found that allows the
hardware to offload segmentation/checksum on tunnels with an outer IPv6

Alexander Duyck 2f8214fe68 ixgbevf: Use mac_ops instead of trying to identify NIC type
This change makes it so that we can just use function pointers instead of
having to identify if a given VF is running on a Linux or Windows PF.  By
doing this we can avoid having to pull too much information out of the
lower layers and can instead just make use of the mac_ops pointers since
they should differ between the two types of VFs anyway.

Amritha Nambiar 1cdaaf5405 ixgbe: Match on multiple headers for cls_u32 offloads
Adds support to set filters with multiple header fields (L3,L4)to match on.
This is achieved in the following order:
1. Create a leaf hash table for the next header.
2. Create a link to the leaf hash table from the base hash table with
   matches on next header type and current header fields.
3. Add filter in leaf hash table with match on next header fields and
   action.

Verified with the following filters :

Match TCP and DIP:
        handle 1: u32 divisor 1
        u32 ht 800: order 1 link 1: \
        offset at 0 mask 0f00 shift 6 plus 0 eat \
        match ip protocol 6 ff match ip dst 10.0.0.1/32
        match tcp src 28 ffff action drop

Delete the filter:

Match on DIP, SIP, UDP (SPort, DPort):
        handle 2: u32 divisor 1
        u32 ht 800: order 2 link 2: \
        offset at 0 mask 0f00 shift 6 plus 0 eat \

Florian Fainelli cf6696608a net: macb: Probe MDIO bus before registering netdev
The current sequence makes us register for a network device prior to
registering and probing the MDIO bus which could lead to some unwanted
consequences, like a thread of execution calling into ndo_open before
register_netdev() returns, while the MDIO bus is not ready yet.

Rework the sequence to register for the MDIO bus, and therefore attach
to a PHY prior to calling register_netdev(), which implies reworking the
error path a bit.

Since commit 3b9d6da67e ("cpu/hotplug: Fix rollback during error-out

CPU_DOWN_PREPARE are processed on the hotplugged CPU. Due to this SMP
function calls are no longer required.

Replace smp_call_function_single() with a direct call to
mvneta_percpu_enable() or mvneta_percpu_disable(). The functions do
not require to be called with interrupts disabled, therefore the
smp_call_function_single() calling convention is not preserved.

Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2016-05-01

This series contains updates to i40e and i40evf.

The theme of this series is code reduction, with several code cleanups in
this series.  Starting with Neerav's removal of the code that implemented
the HMC AQ APIs and calls, since they are now obsolete and not supported
by firmware.

Anjali changes the default of VFs to make sure they are not trusted or
privileged until its explicitly set for trust through the new NDO op
interface.  Also limited the number of MAC and VLAN addresses a VF can
add if it is untrusted/privileged.

Carolyn syncs the VF code for the changes made to the PF for the RSS
hash tuple settings, which ends up cleaning up much of the existing code.

Jesse cleans up compiler warnings which were found with gcc's W=2 option.
Then removed duplicate code, especially since only one copy was actually
being used.

Jacob addresses an issue which was found when testing GCC 6's which
happens to produce new warnings when you left shift a signed value
beyond the storage sizeof the type.  The converts i40e & i40evf to use
the BIT() macro more consistently.

Alex actually bucks the trend of code removal by adding support for
both drivers to use GSO_PARTIAL so that segmentation of frames with
checksums enabled in outer headers is supported.  Fortunately it does
not take much to add this support!

Michal Schmidt 0b86a2a1e5 cxgb3: fix out of bounds read
An out of bounds read of 2 bytes was discovered in cxgb3 with KASAN.

t3_config_rss() expects both arrays it gets as parameters to have
terminators. setup_rss(), the caller, forgets to add a terminator to
one of the arrays. Thankfully the iteration in t3_config_rss() stops
anyway, but in the last iteration the check for the terminator
is an out of bounds read.

Add the missing terminator to rspq_map[].

Arnd Bergmann c489565b53 net/smscx5xx: use the device tree for mac address
This takes the MAC address for smsc75xx/smsc95xx USB network devices
from a the device tree. This is required to get a usable persistent
address on the popular beagleboard, whose hardware designers
accidentally forgot that an ethernet device really requires an a
MAC address to be functional.

The Raspberry Pi also ships smsc9514 without a serial EEPROM, stores
the MAC address in ROM accessible via VC4 firmware.

The smsc75xx and smsc95xx drivers are just two copies of the
same code, so better fix both.

Marek Vasut 70e927b98b mdio_bus: Fix MDIO bus scanning in __mdiobus_register()
Since commit b74766a0a0 ("phylib: don't return NULL
from get_phy_device()") in linux-next, phy_get_device() will return
ERR_PTR(-ENODEV) instead of NULL if the PHY device ID is all ones.

This causes problem with stmmac driver and likely some other drivers
which call mdiobus_register(). I triggered this bug on SoCFPGA MCVEVK
board with linux-next 20160427 and 20160428. In case of the stmmac, if
there is no PHY node specified in the DT for the stmmac block, the stmmac
driver ( drivers/net/ethernet/stmicro/stmmac/stmmac_mdio.c function
stmmac_mdio_register() ) will call mdiobus_register() , which will
register the MDIO bus and probe for the PHY.

The mdiobus_register() resp. __mdiobus_register() iterates over all of
the addresses on the MDIO bus and calls mdiobus_scan() for each of them,
which invokes get_phy_device(). Before the aforementioned patch, the
mdiobus_scan() would return NULL if no PHY was found on a given address
and mdiobus_register() would continue and try the next PHY address. Now,
mdiobus_scan() returns ERR_PTR(-ENODEV), which is caught by the
'if (IS_ERR(phydev))' condition and the loop exits immediately if the
PHY address does not contain PHY.

Repair this by explicitly checking for the ERR_PTR(-ENODEV) and if this
error comes around, continue with the next PHY address.

Alexander Duyck 1c7b4a23d1 i40e/i40evf: Add support for GSO partial with UDP_TUNNEL_CSUM and GRE_CSUM
This patch makes it so that i40e and i40evf can use GSO_PARTIAL to support
segmentation for frames with checksums enabled in outer headers.  As a
result we can now send data over these types of tunnels at over 20Gb/s
versus the 12Gb/s that was previously possible on my system.

The advantage with the i40e parts is that this offload is mostly
transparent as the hardware still deals with the inner and/or outer IPv4
headers so the IP ID is still incrementing for both when this offload is
performed.

Maor Gottlieb 1cabe6b096 net/mlx5e: Create aRFS flow tables
Create the following four flow tables for aRFS usage:
1. IPv4 TCP - filtering 4-tuple of IPv4 TCP packets.
2. IPv6 TCP - filtering 4-tuple of IPv6 TCP packets.
3. IPv4 UDP - filtering 4-tuple of IPv4 UDP packets.
4. IPv6 UDP - filtering 4-tuple of IPv6 UDP packets.

Each flow table has two flow groups: one for the 4-tuple
filtering (full match)  and the other contains * rule for miss rule.

Full match rule means a hit for aRFS and packet will be forwarded
to the dedicated RQ/Core, miss rule packets will be forwarded to
default RSS hashing.

Maor Gottlieb 33cfaaa8f3 net/mlx5e: Split the main flow steering table
Currently, the main flow table is used for two purposes:
One is to do mac filtering and the other is to classify
the packet l3-l4 header in order to steer the packet to
the right RSS TIR.

This design is very complex, for each configured mac address we
have to add eleven rules (rule for each traffic type), the same if the
device is put to promiscuous/allmulti mode.
This scheme isn't scalable for future features like aRFS.

In order to simplify it, the main flow table is split to two flow
tables:
1. l2 table - filter the packet dmac address, if there is a match
we forward to the ttc flow table.

2. TTC (Traffic Type Classifier) table - classify the traffic
type of the packet and steer the packet to the right TIR.

In this new design, when new mac address is added, the driver adds
only one flow rule instead of eleven.

Guillaume Nault 96d934c70d ppp: add rtnetlink device creation support
Define PPP device handler for use with rtnetlink.
The only PPP specific attribute is IFLA_PPP_DEV_FD. It is mandatory and
contains the file descriptor of the associated /dev/ppp instance (the
file descriptor which would have been used for ioctl(PPPIOCNEWUNIT) in
the ioctl-based API). The PPP device is removed when this file
descriptor is released (same behaviour as with ioctl based PPP
devices).

PPP devices created with the rtnetlink API behave like the ones created
with ioctl(PPPIOCNEWUNIT). In particular existing ioctls work the same
way, no matter how the PPP device was created.
The rtnl callbacks are also assigned to ioctl based PPP devices. This
way, rtnl messages have the same effect on any PPP devices.
The immediate effect is that all PPP devices, even ioctl-based
ones, can now be removed with "ip link del".

A minor difference still exists between ioctl and rtnl based PPP
interfaces: in the device name, the number following the "ppp" prefix
corresponds to the PPP unit number for ioctl based devices, while it is
just an unrelated incrementing index for rtnl ones.

David Rivshin d733f7542a drivers: net: cpsw: fix segfault in case of bad phy-handle
If an emac node has a phy-handle property that points to something
which is not a phy, then a segmentation fault will occur when the
interface is brought up. This is because while phy_connect() will
return ERR_PTR() on failure, of_phy_connect() will return NULL.
The common error check uses IS_ERR(), and so missed when
of_phy_connect() fails. The NULL pointer is then dereferenced.

Also, the common error message referenced slave->data->phy_id,
which would be empty in the case of phy-handle. Instead, use the
name of the device_node as a useful identifier. And in the phy_id
case add the error code for completeness.

be in cpsw_slave_data rather than cpsw_priv.

This would go unnoticed in a single emac configuration. But in dual_emac
mode, the last "phy-handle" property parsed for either slave would be used
by both of them, causing them both to refer to the same phy_device.

Jon Cooper dcb4123cbe sfc: disable RSS when unsupported
When certain firmware variants are selected (via the sfboot utility) the
SFC7000 and SFC8000 series NICs don't support RSS. The driver still
tries (and fails) to insert filters with the RSS flag, and the NIC fails
to pass traffic.

When the firmware reports RSS_LIMITED suppress allocating a default RSS
context. The absence of an RSS context is picked up in filter insertion
and RSS flags are discarded.

====================
40GbE Intel Wired LAN Driver Updates 2016-04-27

This series contains updates to i40e and i40evf.

Alex Duyck cleans up the feature flags since they are becoming pretty
"massive", the primary change being that we now build our features list
around hw_encap_features.  Added support for IPIP and SIT offloads,
which should improvement in throughput for IPIP and SIT tunnels with
the offload enabled.

Mitch adds support for configuring RSS on behalf of the VFs, which removes
the burden of dealing with different hardware interfaces from the VF
drivers and improves future compatibility.  Fix to ensure that we do not
panic by checking that the vsi_res pointer is valid before dereferencing
it, after which we can drink beer and eat peanuts.

Shannon does come housekeeping in i40e_add_fdir_ethtool() in preparation
for more cloud filter work.  Added flexibility to the nvmupdate
facility by adding the ability to specify an AQ event opcode to wait on
after Exec_AQ request.

Michal adds device capability which defines if an update is available and
if a security check is needed during the update process.

Kamil just adds a device id to support X722 QSFP+ device.

Greg fixes an issue where a mirror rule ID may be zero, so do not return
invalid parameter when the user passes in a zero for a rule ID.  Adds
support to steer packets to VSIs by VLAN tag alone while being in
promiscuous mode for multicast and unicast MAC addresses.

Jesse fixes the driver from offloading the VLAN tag into the skb any
time there was a VLAN tag and the hardware stripping was enabled, to
making sure it is enabled before put_tag.

v2: Dropped patch 8 ("i40e: Allow user to change input set mask for flow
    director") while Kiran reworks a more generalized solution based
    on feedback from David Miller.

Akinobu Mita 35ef7d689d net: w5100: support W5500
This adds support for W5500 chip.

W5500 has similar register and memory organization with W5100 and W5200.
There are a few important differences listed below but it is still
possible to share common code with W5100 and W5200.

* W5500 register and memory are organized by multiple blocks.  Each one
is selected by 16bits offset address and 5bits block select bits.

But the existing register access operations take u16 address.  This change
extends the addess by u32 address and put offset address to lower 16bits
and block select bits to upper 16bits.

This change also adds the offset addresses for socket register and TX/RX
memory blocks to the driver private data structure in order to reduce
conditional switches for each chip.

* W5500 has the different register offset for socket interrupt mask
register.  Newly added internal functions w5100_enable_intr() and
w5100_disable_intr() take care of the diffrence.

* W5500 has the different register offset for retry time-value register.
But this register is only used to verify that the reset value is correctly
read at initialization.  So move the verification to w5100_hw_reset()
which already does different things for different chips.

Michael Chan 89d0a06c51 bnxt_en: Divide a page into 32K buffers for the aggregation ring if necessary.
If PAGE_SIZE is bigger than BNXT_RX_PAGE_SIZE, that means the native CPU
page is bigger than the maximum length of the RX BD.  Divide the page
into multiple 32K buffers for the aggregation ring.

Add an offset field in the bnxt_sw_rx_agg_bd struct to keep track of the
page offset of each buffer.  Since each page can be referenced by multiple
buffer entries, call get_page() as needed to get the proper reference
count.

Michael Chan 2839f28bd5 bnxt_en: Limit RX BD pages to be no bigger than 32K.
The RX BD length field of this device is 16-bit, so the largest buffer
size is 65535.  For LRO and GRO, we allocate native CPU pages for the
aggregation ring buffers.  It won't work if the native CPU page size is
64K or bigger.

We fix this by defining BNXT_RX_PAGE_SIZE to be native CPU page size
up to 32K.  Replace PAGE_SIZE with BNXT_RX_PAGE_SIZE in all appropriate
places related to the rx aggregation ring logic.

The next patch will add additional logic to divide the page into 32K
chunks for aggrgation ring buffers if PAGE_SIZE is bigger than
BNXT_RX_PAGE_SIZE.

2. Remove unnecessary dependencies between stats and strings.
3. Use counter descriptors which hold a name and offset for each counter,
   and will be used to decide which counters will be exposed.

For example when adding a new software counter to ethtool, instead of:
1. Add to stats struct.
2. Add to strings struct in the same order.
3. Change macro defining number of software counters.
The only thing needed is to link the new counter to a counter descriptor.

VPort counters are a set of hardware traffic counters created automatically
for each virtual port opened.
PPort counters are a set of counters describing per physical port
performance statistics.
These counters are gathered from hardware register and divided to groups
according to different protocols.

Mitch Williams 43a3d9ba34 i40evf: Allow PF driver to configure RSS
If the PF driver reports proper support, allow the PF driver to
configure RSS on the behalf of the VF driver. This will allow for RSS
support on future hardware without changes to the VF driver.

Unfortunately, the old RSS code still needs to stay as the driver needs
to be compatible with PF drivers that don't support this interface. But
this change still simplifies the data structures a bunch and makes this
code simpler to read and maintain.

Maya Erez 349214c1e7 wil6210: prevent deep sleep of 60G device in critical paths
In idle times 60G device can enter deep sleep and turn off
its XTAL clock.
Host access triggers the device power-up flow which will hold
the AHB during XTAL stabilization until device switches from
slow-clock to XTAL clock.
This behavior can stall the PCIe bus for some arbitrary period
of time.
In order to prevent this stall, host can vote for High Latency
Access Policy (HALP) before reading from PCIe bus.
This vote will wakeup the device from deep sleep and prevent
deep sleep until unvote is done.

Alexander Duyck b0fe330643 i40e/i40evf: Clean up feature flags
The feature flags list for i40e and i40evf is beginning to become pretty
massive.  I plan to add another 4 or so features to these drivers and
duplicating the flags for each and every flags list is becoming a bit
repetitive.

The primary change here is that we now build our features list around
hw_encap_features.  After that we assign that to vlan_features,
hw_features, and finally map that onto features.  In addition we end up
throwing features onto hw_encap_features that end up having no effect such
as the Rx offloads and SCTP_CRC.  However that should have no impact and
makes things a bit easier for us as hw_encap_features is one of the less
updated features maps available.

For i40evf I went through and sanity checked a few features as well.
Specifically RXCSUM was being set as a read-only feature which didn't make
much sense.  I have updated things so we can clear the NETIF_F_RXCSUM flag
since that is really a software feature and not a hardware one anyway so

Luca Coelho f0d8f38cd9 iwlwifi: fix fw version reading for DVM devices
In commit 97f95c93c8 ("iwlwifi: remove support for fw older than
-16.ucode") we accidentally changed the fw version reading code for
DVM devices.  The code intended to remove the old fw version API,
because all MVM firmwares version 16 and above that we support don't
use it anymore.  But DVM devices still use the old FW API.

Fix that by bringing the code back in.

Dan Carpenter 81542fac6e brcmfmac: testing the wrong variable in brcmf_rx_hdrpull()
Smatch complains about this code:

    error: we previously assumed '*ifp' could be null (see line 333)

The problem is that we recently changed these from "ifp" to "*ifp" but
there was one that we didn't update.

-       if (ret || !ifp || !ifp->ndev) {
+       if (ret || !(*ifp) || !(*ifp)->ndev) {
                if (ret != -ENODATA && ifp)

-                       ifp->stats.rx_errors++;
+                       (*ifp)->stats.rx_errors++;

I have updated it to *ifp as well.  We always call this function is a
non-NULL "ifp" pointer, btw.

Yuval Mintz fe7cd2bfda qed*: Conditions for changing link
There's some inconsistency in current logic determining whether the
link settings of a given interface can be changed; I.e., in all modes
other than the so-called `deault' mode the interfaces are forbidden from
changing the configuration - but even this rule is not applied to all
user APIs that may change the configuration.

Instead, let the core-module [qed] decide whether an interface can change
the configuration by supporting a new API function. We also revise the
current rule, allowing all interfaces to change their configurations while
laying the infrastructure for future modes where an interface would be
blocked from making such a configuration.

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2016-04-25

This series contains updates to ixgbe and ixgbevf.

Emil provides several patches, starting with the consolidation of the
logic behind configuring spoof checking.  Fixed an issue which was
causing link issues for backplane devices because x550em_a/x devices
did not have a default value for mac->ops.setup_link.  Refactored the
ethtool stats to bring the logic closer to how ixgbe handles stats and
sets up per-queue stats for ixgbevf.

Mark adds a new register to wait for previous register writes to complete
before issuing a register read, which is needed when slower links are
in use.  Fixed the flow control setup for x550em_a, the incorrect
fc_setup function was being used.

Don added a workaround for empty SFP+ cage crosstalk, since on some
systems the crosstalk could lead to link flap on empty SFP+ cages.

Jake converts ixgbe and ixgbevf to use the BIT() macro.

Alex Duyck adds support for partial GSO segmentation in the case of
tunnels for ixgbe and ixgbevf.  Then preps for HyperV by moving the API
negotiation into mac_ops.

Arnd Bergmann provides a fix for the ARM compile warnings in linux-next
by converting the use of a udelay() to msleep().

using BIT macro instead of hand coded bit shifts.

Also fix a few shifts that are shifting values into place by using the

Emil Tantilov d72d6c19b5 ixgbevf: refactor ethtool stats handling
This brings the logic closer to how we handle the stats in ixgbe and it
sets us up for introducing per-queue stats.

Use IXGBEVF_STAT and IXGBEVF_NETDEV_STAT for accessing the driver and
netdev stats respectively. This way we don't have to calculate the
stats based on register values which could lead to the counters not
being initialized properly when the interface is down.

IXGBEVF_QUEUE_STATS_LEN is set to include the number of queues.

Also some defines were renamed to use the IXGBEVF prefix.

Sridhar Samudrala 2a9ed5d1fc ixgbe: make 'action' field in struct ixgbe_fdir_filter a u64 value
This field is used to record the RX queue index for a redirect action
passed via ring_cookie field in struct ethtool_rx_flow_spec which is
a u64 value.

For ex: after adding a filter rule to redirect to a VF using ethtool
  # echo 4 > /sys/class/net/p4p1/device/sriov_numvfs
  # ethtool -N p4p1 flow-type ip4 src-ip 192.168.0.1 action 0x100000000

querying for the rule shows the Action as 'Direct to queue 0'

  # ethtool -n p4p1
  4 RX rings available
  Total 1 rules

  Filter: 2045
 	Rule Type: Raw IPv4
	Src IP addr: 192.168.0.1 mask: 0.0.0.0
	Dest IP addr: 0.0.0.0 mask: 255.255.255.255
	TOS: 0x0 mask: 0xff
	Protocol: 0 mask: 0xff
	L4 bytes: 0x0 mask: 0xffffffff
	VLAN EtherType: 0x0 mask: 0xffff
	VLAN: 0x0 mask: 0xffff
	User-defined: 0x0 mask: 0xffffffffffffffff
	Action: Direct to queue 0

With this fix, ethtool will report the right queue index even for VFs.
	Action: Direct to queue 4294967296

Here 4294967296 corresponds to 0x100000000.
We need to update 'ethtool' to report the queue index as a Hex value so
that it is more  user friendly and matches with the 'action' value that
is passed when adding the rule.

This patch sets mac->ops.setup_link to ixgbe_setup_mac_link_X540 for
X550EM_a/x which is also default for X550. This will result in
mac->ops.setup_link calling the link setup function for the respective

Emil Tantilov d3dec7c7c0 ixgbe: set VLAN spoof checking unconditionally
Previously the PF driver would only set VLAN spoof checking if
the VF had created VLANs. This was done by setting and checking
a counter (vlan_count) whenever a VLAN was created by the VF.
However it is possible for the vlan_count to be !=0 while there are
no VLANs assigned to the VF due to the count incrementing every
time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing
always being set for those VFs.

This patch cleans up the logic by unconditionally setting VLAN based on
how the VF is configured (via ip link set ethX vf Y spoofchk on/off).
This change also resolves an issue where the VLAN spoofing can remain
set even after being disabled by the user due to the driver enabling
VLAN spoof checking every time a VLAN is added to the VF, but would
only allow changes in the setting if vlan_count != 0.

Also default_vf_vlan_id and vlans_enabled were removed from the
vf_data_storage structure since they are not being used in the driver.

Change ixgbe_set_mac_anti_spoofing() to set MAC spoofing per VF similar
to the VLAN and Ethertype functions - this allows us to call the helper
functions in ixgbe_ndo_set_vf_spoofchk() for all spoof check types and

Marek Vasut 3c201b5a84 net: stmmac: socfpga: Remove re-registration of reset controller
Both socfpga_dwmac_parse_data() in dwmac-socfpga.c and stmmac_dvr_probe()
in stmmac_main.c functions call devm_reset_control_get() to register an
reset controller for the stmmac. This results in an attempt to register
two reset controllers for the same non-shared reset line.

The first attempt to register the reset controller works fine. The second
attempt fails with warning from the reset controller core, see below.
The warning is produced because the reset line is non-shared and thus
it is allowed to have only up-to one reset controller associated with
that reset line, not two or more.

The solution has multiple parts. First, the original socfpga_dwmac_init()
is tweaked to use reset controller pointer from the stmmac_priv (private
data of the stmmac core) instead of the local instance, which was used
before. The local re-registration of the reset controller is removed.

Next, the socfpga_dwmac_init() is moved after stmmac_dvr_probe() in the
probe function. This order is legal according to Altera and it makes the
code much easier, since there is no need to temporarily register and
unregister the reset controller ; the reset controller is already registered
by the stmmac_dvr_probe().

Finally, plat_dat->exit and socfpga_dwmac_exit() is no longer necessary,
since the functionality is already performed by the stmmac core.

Hannes Frederic Sowa b7aade1548 vxlan: break dependency with netdev drivers
Currently all drivers depend and autoload the vxlan module because how
vxlan_get_rx_port is linked into them. Remove this dependency:

By using a new event type in the netdevice notifier call chain we proxy
the request from the drivers to flush and resetup the vxlan ports not
directly via function call but by the already existing netdevice
notifier call chain.

I added a separate new event type, NETDEV_OFFLOAD_PUSH_VXLAN, to do so.
We don't need to save those ids, as the event type field is an unsigned
long and using specialized event types for this purpose seemed to be a
more elegant way. This also comes in beneficial if in future we want to
add offloading knobs for vxlan.

Ben Hutchings f43bfaeddc atl2: Disable unimplemented scatter/gather feature
atl2 includes NETIF_F_SG in hw_features even though it has no support
for non-linear skbs.  This bug was originally harmless since the
driver does not claim to implement checksum offload and that used to
be a requirement for SG.

Now that SG and checksum offload are independent features, if you
explicitly enable SG *and* use one of the rare protocols that can use
SG without checkusm offload, this potentially leaks sensitive
information (before you notice that it just isn't working).  Therefore
this obscure bug has been designated CVE-2016-2117.

Tariq Toukan 461017cb00 net/mlx5e: Support RX multi-packet WQE (Striding RQ)
Introduce the feature of multi-packet WQE (RX Work Queue Element)
referred to as (MPWQE or Striding RQ), in which WQEs are larger
and serve multiple packets each.

Every WQE consists of many strides of the same size, every received
packet is aligned to a beginning of a stride and is written to
consecutive strides within a WQE.

In the regular approach, each regular WQE is big enough to be capable
of serving one received packet of any size up to MTU or 64K in case of
device LRO is enabled, making it very wasteful when dealing with
small packets or device LRO is enabled.

For its flexibility, MPWQE allows a better memory utilization
(implying improvements in CPU utilization and packet rate) as packets
consume strides according to their size, preserving the rest of
the WQE to be available for other packets.

MPWQE default configuration:
	Num of WQEs	= 16
	Strides Per WQE = 2048
	Stride Size	= 64 byte

The default WQEs memory footprint went from 1024*mtu (~1.5MB) to
16 * 2048 * 64 = 2MB per ring.
However, HW LRO can now be supported at no additional cost in memory
footprint, and hence we turn it on by default and get an even better
performance.

Performance tested on ConnectX4-Lx 50G.
To isolate the feature under test, the numbers below were measured with
HW LRO turned off. We verified that the performance just improves when
LRO is turned back on.

* Netperf single TCP stream:
- BW raised by 10-15% for representative packet sizes:
  default, 64B, 1024B, 1478B, 65536B.

* Netperf multi TCP stream:
- No degradation, line rate reached.

* Pktgen: packet rate raised by 2-10% for traffic of different message
sizes: 64B, 128B, 256B, 1024B, and 1500B.

* Pktgen: packet loss in bursts of small messages (64byte),
single stream:
- | num packets | packets loss before | packets loss after
  |     2K      |       ~ 1K          |       0
  |     8K      |       ~ 6K          |       0
  |     16K     |       ~13K          |       0
  |     32K     |       ~28K          |       0
  |     64K     |       ~57K          |     ~24K

As expected as the driver can receive as many small packets (<=64B) as
the number of total strides in the ring (default = 2048 * 16) vs. 1024
(default ring size regardless of packets size) before this feature.

fm10k_tlv_parse_attr is supposed to return FM10K_NOT_IMPLEMENTED for any
TLV who's attribute id lies outside the range of results. It does not do
this today. In addition, the documentation does not indicate that other
attributes which are not implemented for a given TLV will be silently
ignored. Fix this. Clean up the logic so that we don't rely on the fact
that FM10K_NOT_IMPLEMENTED is greater than zero, as this can easily
cause confusion.

A future extension could look into some way of reporting unknown TLVs
in order to make issues more easily discoverable. We can't just return
FM10K_NOT_IMPLEMENTED here because we don't want to drop the entire
message if it has an unknown TLV.

Jacob Keller 3417415c3a fm10k: do not disable PCI device in fm10k_io_error_detected
fm10k_io_error_detected() does not need to call pci_disable_device(). In
the cases where the reset needs to occur, the stack flow will result in
calling fm10k_remove() which already disables the PCI device. If we
leave the pci_disable_device(), we result in a warning about disabling
an already disabled device.

Many PCI drivers do call pci_disable_device() in their .error_detected()
routines, but it does not appear to be required. In addition, these
drivers have a check "is_pci_enabled()" call in their remove routines,
which is how they chose to handle the duplicate device disable.

This seems incorrect, since the PCI device structure is reference
counted. It is very possible that the reference count for the PCI device
could be greater than 1. In this case, you would remove the PCI device
within the error_detected routine, reducing count to 1, then remove it
again in the remove function, reducing it to zero. This would result in
yet another disable somewhere else failing. Thus, we shouldn't be using
is_pci_enabled() to check for this issue. Instead, just remove the
extraneous pci_device_disable() found within the error_detected routine.

Jacob Keller a7a7783ada fm10k: correctly handle LPORT_MAP error
Currently, any error responses from the switch manager after an
LPORT_MAP request are silently ignored. At most the mailbox message will
be reported as an error. This can result in unexpected behavior when the
switch manager has configured a port with zero bandwidth. Add support
for reading the fm10k_swapi_error structure from LPORT_MAP responses.

If the message contains the necessary TLV and has a non-zero error code,
report link down, clear the dglort_map, and delay the next
get_host_state call by a reasonable delay. Also log an error message
indicating that the LPORT_MAP request failed.

The delay ensures preventing an interrupt storm on the switch manager,
and reduces the number of mailbox messages we send in this scenario
drastically.

Ngai-Mint Kwan 8998763a7b fm10k: Fix multicast mode sync issues
Multicast mode checking is no longer a requirement to perform unicast
and multicast address syncs. Specifically, a device operating in
promiscuous and/or all multicast mode is not excluded. The issue occurs
when the netdev is pre-configured to either multicast mode and is
enabled for the first time. The multicast-group table in the Switch
Manager will be missing obvious multicast entries associated to this
netdev.

Changes were also made to disallow unicast and multicast syncs with
VLAN 0. The Switch Manager considers VLAN 0 to be an invalid entry.
Requests with VLAN 0 by the netdev are only generated when the driver is
freshly installed and the default VID is not set.

I expierenced when setting channel while sleep mode it didn't changed
the channel inside the hardware registers. Then I got another report of
an user which has similar issues.

I increased the sleep to off state change timing, which is according
at86rf233 at maximum 1000 us. After this change I got no similar effects
again.

I tried another option to wait on AWAKE_END irq, which can be used to
wait until the transceiver is awaked. I tested it and the IRQ took 4
seconds after starting state change. I don't believe it takes 4 seconds
to go into the TRX_OFF state from SLEEP state. The alternative is to
increase the timings which seems to work.

And after the change it is as follows:

Zefir Kurtisi 71f5137bf0 ath9k: interpret requested txpower in EIRP domain
Tx power limitations at upper layers are interpreted in
the EIRP domain. When the user requests a given maximum
txpower, e.g. with: 'iw phy0 set txpower fixed 1500',
he expects the EIRP to be at or below 15dBm.

In ath9k_hw_apply_txpower(), the interpretation is
different: the antenna-gain is capped against the
current txpower limit in the regulatory, but not
against the user set value. It ensures that the
resulting EIRP is below the limit defined by the
active countrycode, but not below the value the
user requested.

In a scenario like e.g.
 a) antenna_gain=6
 b) countrycode limits to eirp=18
 c) user set txpower=15
this will cause a setting for AR_PHY_POWER_TX_RATE
regs resulting in an EIRP > 15.

This patch ensures that antenna-gain is considered
whenever the txpower limit is adjusted and with that
the user set limits are kept.

Raja Mani 7e247a9e88 ath10k: add dynamic tx mode switch config support for qca4019
push-pull mode needs certain amount the host driver involvement for
managing queues in the host memory and packet delivery to firmware.
qca4019 wifi firmware has an option to stay in push mode for less
number of active traffic flow and then switch to push-pull mode when
the active traffic flow goes beyond the certain limit.

The advantage of staying in push mode for less active traffic is, the
host cpu consumption is reduced. qca4019 firmware supports this
flexibility of the mode switch. It takes the host driver interest
(LOW_PERF/HIGH_PERF) via WMI_EXT_RESOURCE_CFG_CMDID,

 LOW_PERF  - fw would stay in push mode and switch to push-pull
               based on demand.
 HIGH_PERF - fw would stay in push-pull mode from the boot.

To make this configuration generic, new WMI services
WMI_SERVICE_TX_MODE_PUSH_ONLY, WMI_SERVICE_TX_MODE_PUSH_PULL,
WMI_SERVICE_TX_MODE_DYNAMIC are introduced to take dynamic tx mode
switch support availability in firmware.
Based on WMI_SERVICE_TX_MODE_DYNAMIC, LOW_PERF or HIGHT_PERF is
configured to the firmware.

Rajkumar Manoharan 1ce8c1484e ath10k: fix rx_channel during hw reconfigure
Upon firmware assert, restart work will be triggered so that mac80211
will reconfigure the driver. An issue is reported that after restart
work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info
for operating channel. During reconfigure, since mac80211 already has
valid channel context for given radio, channel context iteration return
num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning
channel context to rx_channel when driver restart is in progress.

KY Srinivasan 84bf9cefb1 hv_netvsc: Implement support for VF drivers on Hyper-V
Support VF drivers on Hyper-V. On Hyper-V, each VF instance presented to
the guest has an associated synthetic interface that shares the MAC address
with the VF instance. Typically these are bonded together to support
live migration. By default, the host delivers all the incoming packets
on the synthetic interface. Once the VF is up, we need to explicitly switch
the data path on the host to divert traffic onto the VF interface. Even after
switching the data path, broadcast and multicast packets are always delivered
on the synthetic interface and these will have to be injected back onto the
VF interface (if VF is up).
This patch implements the necessary support in netvsc to support Linux
VF drivers.

Jakub Kicinski 3d780b926a nfp: add async reconfiguration mechanism
Some callers of nfp_net_reconfig() are in atomic context so
we used to busy wait for commands to complete.  In worst case
scenario that means locking up a core for up to 5 seconds
when a command times out.  Lets add a timer-based mechanism
of asynchronously checking whether reconfiguration completed
successfully for atomic callers to use.  Non-atomic callers
can now just sleep.

The approach taken is quite simple because (1) synchronous
reconfigurations always happen under RTNL (or before device
is registered); (2) we can coalesce pending reconfigs.
There is no need for request queues, timer which eventually
takes a look at reconfiguration result to report errors is
good enough.

Dinh Nguyen f66bc94174 stmmac: socfpga: remove extra call to socfpga_dwmac_setup
In the socfpga_dwmac_probe function, we have a call to socfpga_dwmac_setup,
which is already called from socfpga_dwmac_init later in the probe function.
Remove this extra call to socfpga_dwmac_setup.

Also we should not be calling socfpga_dwmac_setup() directly without wrapping
it around the proper reset assert/deasserts. That is because the
socfpga_dwmac_setup() is setting up PHY modes in the system manager, and it
is requires the EMAC's to be in reset during the PHY setup.

Alexander Duyck aed069df09 ip_tunnel_core: iptunnel_handle_offloads returns int and doesn't free skb
This patch updates the IP tunnel core function iptunnel_handle_offloads so
that we return an int and do not free the skb inside the function.  This
actually allows us to clean up several paths in several tunnels so that we
can free the skb at one point in the path without having to have a
secondary path if we are supporting tunnel offloads.

In addition it should resolve some double-free issues I have found in the
tunnels paths as I believe it is possible for us to end up triggering such
an event in the case of fou or gue.

Vivien Didelot 207afda1b5 net: dsa: mv88e6xxx: share the same default FDB
For hardware cross-chip bridging to work, user ports *and* DSA ports
need to share a common address database, in order to switch a frame to
the correct interconnected device.

This is currently working for VLAN filtering aware systems, since Linux
will implement a bridge group as a 802.1Q VLAN, which has its own FDB,
including DSA and CPU links as members.

However when the system doesn't support VLAN filtering, Linux only
relies on the port-based VLAN to implement a bridge group.

To fix hardware cross-chip bridging for such systems, set the same
default address database 0 for user and DSA ports, instead of giving
them all a different default database.

Note that the bridging code prevents frames to egress between unbridged
ports, and flushes FDB entries of a port when changing its STP state.

Also note that the FID 0 is special and means "all" for ATU operations,
but it's OK since it is used as a default forwarding address database.

Fixes: 2db9ce1fd9 ("net: dsa: mv88e6xxx: assign default FDB to ports")
Fixes: 466dfa0770 ("net: dsa: mv88e6xxx: assign dynamic FDB to bridges")
