Catherine Sullivan dc5b4e9fad i40e/i40evf: Reset VLAN filter count when resetting
When we do a reset, all the VLAN filters get added again. Therefore we also
want to reset the VLAN count to 0 or we quickly run out of filters.

Aviv Heller 7907f23adc net/mlx5: Implement RoCE LAG feature
Available on dual port cards only, this feature keeps
track, using netdev LAG events, of the bonding
and link status of each port's PF netdev.

When both of the card's PF netdevs are enslaved to the
same bond/team master, and only them, LAG state
is active.

During LAG, only one IB device is present for both ports.

In addition to the above, this commit includes FW commands
used for managing the LAG, new facilities for adding and removing
a single device by interface, and port remap functionality according to
bond events.

Please note that this feature is currently used only for mimicking
Ethernet bonding for RoCE - netdevs functionality is not altered,
and their bonding continues to be managed solely by bond/team driver.

Aviv Heller 84df61ebc6 net/mlx5: Add HW interfaces used by LAG
Exposed LAG commands enum and layouts:
- CREATE_LAG
  HW enters LAG mode:
  RoCE traffic from port two is received on PF0 core dev.
  Allows to set tx_affinity (tx port) for QPs and TISes.
  Allows to port remap QPs and TISes, overriding their
  tx_affinity behavior.

- MODIFY_LAG
  Remap QPs and TISes to another port.

- QUERY_LAG
  Query whether LAG mode is active.

- DESTROY_LAG
  HW exits LAG mode, returning to non-LAG behavior.

- CREATE_VPORT_LAG
  Merge Ethernet flow steering, such that traffic received on port
  two jumps to PF0 root flow table.

  Available only in LAG mode.

- DESTROY_VPORT_LAG
  Ethernet flow steering returns to non-LAG behavior.

Caps added:
- lag_master
  Driver is in charge of managing the LAG.
  This is currently the only option.

- num_lag_ports
  LAG is supported only if this field's value is 2.

Other fields:
- QP/TIS tx port affinity
  During LAG, this field controls on which port a QP or TIS resides.

- TIS strict tx affinity
  When this field is set, the TIS will not be subject to port remap by
  CREATE_LAG/MODIFY_LAG.

- LAG demux flow table
  Flow table used for redirecting non user-space traffic back to
  PF1 root flow table, if the packet was received on port two.

WANG Cong 22dc13c837 net_sched: convert tcf_exts from list to pointer array
As pointed out by Jamal, an action could be shared by
multiple filters, so we can't use list to chain them
any more after we get rid of the original tc_action.
Instead, we could just save pointers to these actions
in tcf_exts, since they are refcount'ed, so convert
the list to an array of pointers.

The "ugly" part is the action API still accepts list
as a parameter, I just introduce a helper function to
convert the array of pointers to a list, instead of
relying on the C99 feature to iterate the array.

====================
Intel Wired LAN Driver Updates 2016-08-16

This series contains fixes to e1000e, igb, ixgbe and i40e.

Kshitiz Gupta provides a fix for igb to resolve the PHY delay compensation
math in several functions.

Jarod Wilson provides a fix for e1000e which had to broken up into 2
patches, first is prepares the driver for expanding the list of NICs
that have occasional ~10 hour clock jumps when being used for PTP.
Second patch actually fixes i218 silicon which has been experiencing
the clock jumps while using PTP.

Alex provides 2 patches for ixgbe now that he is back at Intel.  First
fixes setting VLNCTRL.VFE bit, which was left unchanged in earlier patches
which resulted in disabling VLAN filtering for all the VFs.  Second
corrects the support for disabling the VLAN tag filtering via the
feature bit.

Lastly, David fixes i40e which was causing a kernel panic when
non-contiguous traffic classes or traffic classes not starting with TC0,
were configured on a link partner switch.  To fix this, changed the
logic when determining the total number of TCs enabled.

Ido Schimmel 9ffcc3725f mlxsw: spectrum: Allow packets to be trapped from any PG
When packets enter the device they are classified to a priority group
(PG) buffer based on their PCP value. After their egress port and
traffic class are determined they are moved to the switch's shared
buffer and await transmission, if:

(Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres &&
 Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres)
||
(Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min ||
 Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min)

Packets scheduled to transmission through CPU port (trapped to CPU) use
traffic class 7, which has a zero maximum and minimum quotas. However,
when such packets arrive from PG 0 they are admitted to the shared
buffer as PG 0 has a non-zero minimum quota.

Allow all packets to be trapped to the CPU - regardless of the PG they
were classified to - by assigning a 10KB minimum quota for CPU port and
TC7.

Commit bbf2a4757b ("mlxsw: spectrum: Initialize ports at the end of

sequence, which means ports are the first to be removed during fini.

Since the FDB delayed work is still active when ports are removed it's
possible for it to process FDB notifications of inactive ports,
resulting in a warning message.

Fix that by marking ports as inactive only after unregistering them. The
NETDEV_UNREGISTER event will invoke bridge's driver port removal
sequence that will cause the FDB (and FDB notifications) to be flushed.

mlx5_cmd_exec to simplify the interface.

Also we do here some cleanup for redundant software structures
(inbox/outbox) and functions and improved command failure output.

Saeed Mahameed 1a412fb1ca {net,IB}/mlx5: Modify QP commands via mlx5 ifc
Prior to this patch we assumed that modify QP commands have the
same layout.

In ConnectX-4 for each QP transition there is a specific command
and their layout can vary.

e.g: 2err/2rst commands don't have QP context in their layout and before
this patch we posted the QP context in those commands.

Fortunately the FW only checks the suffix of the commands and executes
them, while ignoring all invalid data sent after the valid command
layout.

This patch removes mlx5_modify_qp_mbox_in and changes
mlx5_core_qp_modify to receive the required transition and QP context
with opt_param_mask if needed.  This way the caller is not required to
provide the command inbox layout and it will be generated automatically.

mlx5_core_qp_modify will generate the command inbox/outbox layouts
according to the requested transition and will fill the requested
parameters.

Dave Ertman fbfe12c64f i40e: check for and deal with non-contiguous TCs
The i40e driver was causing a kernel panic when
non-contiguous Traffic Classes, or Traffic Classes not
starting with TC0, were configured on a link partner switch.
i40e does not support non-contiguous TCs.

To fix this, the patch changes the logic when determining
the total number of TCs enabled.  Before, this would use the
highest TC number enabled and assume that all TCs below it were
also enabled.  Now, we create a bitmask of enabled TCs and scan
it to determine not only the number of TCs, but also if the set
of enabled TCs starts at zero and is contiguous.  If not, then
DCB is disabled by only returning one TC.

When I was adding the code for enabling VLAN promiscuous mode with SR-IOV

assumed there was code in another path that was setting it when we enabled
SR-IOV.  This wasn't the case and as a result we were just disabling VLAN
filtering for all the VFs apparently.

Also the previous patches were always clearing CFIEN which was always set
to 0 by the hardware anyway so I am dropping the redundant bit clearing.

This is prepatory work for an expanding list of adapter families that have
occasional ~10 hour clock jumps when being used for PTP. Factor out the
sanitization function and convert to using a feature (bug) flag, per

Littering functional code with device-specific checks is much messier than
simply checking a flag, and having device-specific init set flags as needed.
There are probably a number of other cases in the e1000e code that
could/should be converted similarly.

Kshitiz Gupta 0066c8b6f4 igb: fix adjusting PTP timestamps for Tx/Rx latency
Fix PHY delay compensation math in igb_ptp_tx_hwtstamp() and
igb_ptp_rx_rgtstamp. Add PHY delay compensation in
igb_ptp_rx_pktstamp().

In the IGB driver, there are two functions that retrieve timestamps
received by the PHY - igb_ptp_rx_rgtstamp() and igb_ptp_rx_pktstamp().
The previous commit only changed igb_ptp_rx_rgtstamp(), and the change
was incorrect.

There are two instances in which PHY delay compensations should be
made:

- Before the packet transmission over the PHY, the latency between
  when the packet is timestamped and transmission of the packets,
  should be an add operation, but it is currently a subtract.

- After the packets are received from the PHY, the latency between
  the receiving and timestamping of the packets should be a subtract
  operation, but it is currently an add.

sean.wang@mediatek.com b2025c7cc9 net: ethernet: mediatek: fix flow control settings on GMAC0 is not being enabled properly
Commit 08ef55c6f2
("net-next: mediatek: fix gigabit and flow control advertisement")
had supported proper flow control settings for GMAC1. But for GMAC0,

1.GMAC0 shares the common logic with GMAC1 inside mtk_phy_link_adjust()
to adapt various settings for the target phy.

2.GMAC0 uses fixed-phy to connect to a builtin gigabit switch with
fixed link speed as commit 0c72c50f6f
("net-next: mediatek: add fixed-phy support") describes.

3.However, fixed-phy doesn't enable SUPPORTED_Pause & SUPPORTED_Asym_Pause
supported flag on default that would cause mtk_phy_link_adjust() not to
enable flow control setting on GMAC0 properly and cause packet dropped
when high traffic.

Due to these reasons, the patch adds SUPPORTED_Pause & SUPPORTED_Asym_Pause
supported flags on fixed-phy used by the driver to have proper handling on
the both GMAC with the shared common logic.

Hariprasad Shenai 7829451c69 cxgb4: Add control net_device for configuring PCIe VF
Issue:
For instance, the current APIs assume a 1-to-1 mapping of Network Ports,
Physical Functions and the SR-IOV Virtual Functions of those Physical
Functions. This is not the case with our cards where any Virtual
Function can be hooked up to any Port -- or any number of Ports the
current Linux APIs also assume only 1 Network Interface/Port can be
accessed per Virtual Function.

Another issue is that these APIs assume that the Administrative Driver
is attached to the Physical Function Associated with a Virtual Function.
This is not the case with our card where all administration is performed
by a Driver which is not attached to any of the Physical Functions which
have SR-IOV PCI Capabilities.

Another consequence of these assumptions is the inability to utilize all
of the cards SR-IOV resources. For instance, our cards have SR-IOV
Capabilities on Physical Functions 0..3 and the administrative Driver
attaches to Physical Function 4. Each of the Physical Functions 0..3 can
support up to 16 Virtual Functions. With the current Linux APIs, a
2-Port card would only be able to use the Virtual Functions on Physical
Function 0..1 and not allow the Virtual Functions on Physical Functions
2..3 to be used since there are no Ports 2..3 on a 2-Port card.

Fix:
Since the control node is always the netdevice for all VF ACL commands.
Created a dummy netdevice for each Physical Function from 0 to 3 through
which one could control their VFs. The device won't be associated with
any port, since it doesn't need to transmit/receive. Its purely used
for VF management purpose only. The device will be registered only when
VF for a particular PF is configured using PCI sysfs interface and
unregistered while pci_disable_sriov() for the PF is called.

Jiri Kosina e87a8f24c9 net: resolve symbol conflicts with generic hashtable.h
This is a preparatory patch for converting qdisc linked list into a
hashtable. As we'll need to include hashtable.h in netdevice.h, we first
have to make sure that this will not introduce symbol conflicts for any of
the netdevice.h users.

Niklas Söderlund 0184165b2f ravb: add sleep PM suspend/resume support
The interface would not function after the system had been woken up
after have been suspended (echo mem > /sys/power/state) cycle. The
reason for this is that all device registers have been reset to its
default values. This patch adds sleep suspend and resume functions that
detached the interface at suspend and restore the registers and reattach
the interface at resume.

Only the registers that are only configured at probe time needs to be
explicitly restored by the resume handler. All other registers are
reconfigured by either reopening the device in the resume handler (if
the device was running when the system was suspended) or when the
interface is opened by a user at a later time.

Sylwester Nawrocki a96d3b7593 dm9000: Fix irq trigger type setup on non-dt platforms
Commit b5a099c67a "net: ethernet: davicom: fix devicetree irq
resource" causes an interrupt storm after the ethernet interface
is activated on S3C24XX platform (ARM non-dt), due to the interrupt
trigger type not being set properly.

It seems, after adding parsing of IRQ flags in commit 7085a7401b
"drivers: platform: parse IRQ flags from resources", there is no path
for non-dt platforms where irq_set_type callback could be invoked when
we don't pass the trigger type flags to the request_irq() call.

In case of a board where the regression is seen the interrupt trigger
type flags are passed through a platform device's resource and it is
not currently handled properly without passing the irq trigger type
flags to the request_irq() call.  In case of OF an of_irq_get() call
within platform_get_irq() function seems to be ensuring required irq_chip
setup, but there is no equivalent code for non OF/ACPI platforms.

This patch mostly restores irq trigger type setting code which has been
removed in commit ("net: ethernet: davicom: fix devicetree irq resource").

This happens because CPSW allocates SK buffers and then passes
pointers on them in CPDMA where they stored in internal CPPI RAM
(SRAM) which belongs to DEV MMIO space. Kmemleak does not scan IO
memory and so reports memory leaks.

Hence, mark allocated sk buffers as false positive explicitly.

Grygorii Strashko aeec302104 net: ethernet: ti: cpdma: remove used_desc counter
The struct cpdma_desc_pool->used_desc field can be safely removed from
CPDMA driver (and hot patch) because used_descs counter is used just
for pool consistency check at CPDMA deinitialization and now this
check can be re-implemnted using gen_pool_size(pool->gen_pool) !=
gen_pool_avail(pool->gen_pool).
More over, this will allow to get rid of warnings in
cpdma_desc_pool_destro()-> WARN_ON(pool->used_desc) which may happen
because the used_descs is used unprotected, since CPDMA has been
switched to use genalloc, and may get wrong values on SMP.

Hence, remove used_desc from struct cpdma_desc_pool.

Sathya Perla b71724147e be2net: replace polling with sleeping in the FW completion path
The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with
BHs disabled. The driver currently issues the required cmds to the FW in
these contexts and polls on completions from the FW, while BHs remain
disabled.  This can cause either packet loss or packet reception to be
delayed on that CPU.

This patch defers processing of the above cmds to a separate workqueue.
With this change, FW cmds are now issued only in process context.
Now that the FW cmds are issued only in process context, they can sleep
waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock)
calls are now replaced with mutex calls.

Also a new rx_filter_lock is now needed to protect the RX filtering fields
like vids[] between be_vlan_add/rem_vid() and __be_set_rx_mode() contexts.

Sriharsha Basavapatna 92fbb1df83 be2net: Avoid unnecessary firmware updates of multicast list
Eachtime the ndo_set_rx_mode() routine is called, the driver programs the
multicast list in the adapter without checking if there are any changes to
the list. This leads to a flood of RX_FILTER cmds when a number of vlan
interfaces are configured over the device, as the ndo_ gets
called for each vlan interface. To avoid this, we now use __dev_mc_sync()
and __dev_uc_sync() API, but only to detect if there is a change in the
mc/uc lists. Now that we use this API, the code has to be-designed to
issue these API calls for each invocation of the be_set_rx_mode() call.
