Gratuitously notify VFs of link state when they activate their queues.
In general, this is the last thing that a VF driver will do as it opens
its interface, so this is a good time to notify the VF.
Currently, VF devices assume link is up unless told otherwise, which
means that VFs instantiated on a PF with no link will report the wrong
state. This change corrects that issue.

Explicitly stop the rings belonging to each VF when disabling SR-IOV.
Even though the VFs were gone, and the associated VSIs were removed,
the rings were not stopped, and in some circumstances the hardware would
continue to access the memory formerly used by the rings, causing
memory corruption or DMAR errors, both of which would lead to general
malaise of the kernel.
To relieve this condition, explicitly stop all the rings associated with

When we call update_max_size it does not drop all oversized messages.
This is due to the difficulty in performing this operation, since it is
a FIFO which makes updating anything other than head or tail very
difficult. To fix this, modify validate_msg_size to ensure that we error
out later when trying to transmit the message that could be oversized.
This will generally be a rare condition, as it requires the FIFO to
include a message larger than the max_size negotiated during mailbox
connect. Note that max_size is always smaller than rx.size so it should
be safe to use here.
Also, update the update_max_size function header comment to clearly
indicate that it does not drop all oversized messages, but only those at
the head of the FIFO.

When we forcefully shutdown the mailbox, we then go about resetting max

Since we already schedule the service task, we can just wait for this
task to handle the mailbox events from the VF. This reduces some complex
code flow, and makes it so we have a single path for handling the VF
messages. There is a possibility that we have a slight delay in handling
VF messages, but it should be minimal.
The result of tx_complete and !rx_ready is insufficient to determine
whether we need to process the mailbox. There is a possible race
condition whereby the VF fills up the mbmem for us, but we have already
recently processed the mailboxes in the interrupt. During this time,
the interrupt is disabled. Thus, our Rx FIFO is empty, but the mbmem now
has data in it. Since we continually check whether Rx FIFO is empty, we
then never call process. This results in the possibility to prevent PF
from handling the VF mailbox messages.
Instead, just call process every time, despite the fact that we may or
may not have anything to process for the VF. There should be minimal
overhead for doing this, and it resolves an issue where the VF never
comes up due to never getting response for its SET_LPORT_STATE message.

Since we run the watchdog periodically, which might take a while and
potentially monopolize the system default workqueue, create our own
separate work queue. This also helps reduce and stabilize latency
between scheduling the work in our interrupt and actually performing
the work. Still use a timer for the regular scheduled interval but
queue the work onto its own work queue.
It seemed overkill to create a single workqueue per interface, so we
just spawn a single work queue for all interfaces upon driver load. For
this reason, use a multi-threaded workqueue with one thread per
processor, rather than single threaded queue.

82599 and x540 VFs and PF share the same RSS redirection table (RETA).
Therefore we just return it for all VFs.
For 82599 and x540 RETA table is an array of 32 registers (128 bytes) and
the maximum number of registers that may be delivered in a single VF-PF
channel command is 15. On the other hand VFs of these devices can be
configured to have up to 4 RSS queues. Therefore we will "compress" the
RETA by transferring only 2 bits per entry and thereby it will take only 8
registers (DWORDS) to transfer the whole VF RETA.
Thus this patch does the following:
- Adds a new API version (to specify a new commands set).
- Adds the IXGBE_VF_GET_RETA command to the VF-PF commands set.

This does not affect the Virtual channel API as such but it changes the
meaning of what is communicated to the VSI resource struct as vsi_id.
Earlier vsi_idx was being passed in, which was the index in the PF's VSI
array. Now we pass vsi_id as communicated by the FW to the driver.
This will help with future expansion of VF and FW communication.
With this in place now the VF and Virtual channel driver change to move over
to VSI id use is complete and is validated.

ptp: get ready for 2038
This series converts the core driver methods of the PTP Hardware Clock
(PHC) subsystem to use the 64 bit version of the timespec structure,
making the core API ready for the year 2038.
In addition, I reviewed how each driver and device represents the time
value at the hardware register level. Most of the drivers are ready,
but a few will need some work before the year 2038, as shown:
Patch Driver
------------------------------------------------
12 drivers/net/ethernet/intel/igb/igb_ptp.c
15 ? drivers/net/ethernet/sfc/ptp.c
16 drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c
The commit log messages document how each driver is ready or why it is
not ready. For patch 15, I could not easily find out the hardware
representation of the time value, and so the SFC maintainers will have
to review their low level code in order to resolve any remaining
issues.
* ChangeLog
** V3
- dp83640: use timespec64 throughout per Arnd's suggestion
- tilegx: use timespec64 throughout per Chris' suggestion

This is resolved by delaying the releasing of resources until we
receive acknowledgment from the PF driver that the rings have indeed

Call the netdev carrier off and TX disable functions first, before other
shutdown operations. This stops the stack from hitting us with
transmits while we're shutting down. Additionally, disable NAPI before
disabling interrupts, or the interrupt might get re-enabled
inappropriately. Finally, remove the call to netif_tx_stop_all_queues,
as it is redundant - the call to netif_tx_disable already did the same
thing.

When the VF interface is closed, we cannot immediately free our rings

To fix this, delay releasing resources until we receive acknowledgment

The NVMUpdate tool doesn't necessarily know the ReadOnly map of the current
NVM image, and must try reading and writing words that may be protected.
This generates an error out of the Firmware request that the driver logs.
Unfortunately, this ends up spitting out hundreds of bogus read and write
error message that looks rather messy.
This patch checks the error type and under normal conditions will not print
the typical read and write errors during NVMUpdate. This can be overridden
by enabling the NVM update debugging. This results in a much less messy log
file, and likely many fewer customer support questions.

Since GLQF_FDCNT_0 register now has the right offset, use it to simplify our
FD flush flow.
If the filter add error happens to be for SB we just auto disable SB.
If filter error happens to be for ATR, auto disable ATR and mark
the state to FD_FLUSH_REQUESTED. Which gets cleared when flush completes.
If we are entering flush too quickly (< 30 seconds) and we have quite
a few SB rules, its time to disable ATR for good. Since SB + ATR rules
is most likely making the FD table unstable.
ATR can be re-enabled by turning ntuple off (ethtool -K ntuple off)
and will remain off after turning ntuple on till it gets unstable again.

The initial problem solved here is that the vector allocation was trying
too hard to save vectors for VMDq, to the point of not giving the PF enough
when in a tight situation such as an NPAR partition. This change makes
sure that the PF will get all the queues and vectors it wants to fill
out its destiny. Essentially, nothing is specially reserved for VMDq,
it simply gets whatever is left after the PF, FCoE, and FD sideband get
what they want.
Additionally, the calculations for the reservations were harder to follow
than necessary, so I've made it more straight forward.

There is a race condition between e1000_change_mtu's cleanups and
netpoll, when we change the MTU across jumbo size:
Changing MTU frees all the rx buffers:
e1000_change_mtu -> e1000_down -> e1000_clean_all_rx_rings ->
e1000_clean_rx_ring
Then, close to the end of e1000_change_mtu:
pr_info -> ... -> netpoll_poll_dev -> e1000_clean ->
e1000_clean_rx_irq -> e1000_alloc_rx_buffers -> e1000_alloc_frag
And when we come back to do the rest of the MTU change:
e1000_up -> e1000_configure -> e1000_configure_rx ->
e1000_alloc_jumbo_rx_buffers
alloc_jumbo finds the buffers already != NULL, since data (shared with
page in e1000_rx_buffer->rxbuf) has been re-alloc'd, but it's garbage,
or at least not what is expected when in jumbo state.
This results in an unusable adapter (packets don't get through), and a
NULL pointer dereference on the next call to e1000_clean_rx_ring
(other mtu change, link down, shutdown):

When bringing down an interface netif_carrier_off() should be
one the first things we do, since this will prevent the stack
from queuing more packets to this interface.
This operation is very fast, and should make the device behave
much nicer when trying to bring down an interface under load.
Also, this would Do The Right Thing (TM) if this device has some
sort of fail-over teaming and redirect traffic to the other IF.

Intel Wired LAN Driver Updates 2015-03-03
This series contains updates to fm10k, i40e and i40evf.
Matthew updates the fm10k driver by cleaning up code comments and whitespace
issues. Also modifies the tunnel length header check, to make it more robust
by calculating the inner L4 header length based on whether it is TCP or UDP.
Implemented ndo_features_check() that allows drivers to report their offload
capabilities per-skb.
Neerav updates the i40e driver to skip over priority tagging if DCB is not
enabled. Fixes an issue where the driver is not flushing out the
DCBNL app table for applications that are not present in the local DCBX
application configuration TLVs. Fixed i40e where, in the case of MFP
mode, the driver was returning the incorrect number of traffic classes
for partitions that are not enabled for iSCSI. Even though the driver
was not configuring these traffic classes in the transmit scheduler for
the NIC partitions, it does use this map to setup the queue mappings.
Shannon updates i40e/i40evf to include the firmware build number in the
formatted firmware version string.
Akeem adds a safety net (by adding a 'default' case) for the possible
unmatched switch calls.
Mitch updates i40e to not automatically disable PF loopback at runtime,
now that we have the functionality to enable and disable PF loopback. This
fix cleans up a bogus error message when removing the PF module with VFs
enabled. Adds a extra check to make sure that the indirection table
pointer is valid before dereferencing it.
Anjali enables i40e to enable more than the max RSS qps when running in a
single TC mode for the main VSI. It is possible to enable as many as
num_online_cpus(). Adds a firmware check to ensure that DCB is disabled for
firmware versions older than 4.33. Updates i40e/i40evf to add missing
packet types for VXLAN offload. Updated i40e to be able to handle varying
RSS table size for each VSI, since all VSI's do not have the same RSS table
size.
v2: Dropped previous patch #9 "i40e/i40evf: Add capability to gather VEB
per TC stats" since the stats should be in ethtool and not debugfs.
