This has been sitting in -next for ages. All MIPS _defconfigs have

pch_gbe_xmit_frame skb->len verification was incorrect in vlan case
causing bogus transfer length errors. One correction could be:
offset = skb->protocol == htons(ETH_P_8021Q) ? 0 : 4;
if (unlikely(skb->len > (adapter->hw.mac.max_frame_size - offset)))
However, this verification is not necessary, so remove it.

Currently the mlx4 drivers don't have the necessary callbacks to
implement EEH errors detection and recovery, so the PCI layer uses the
probe and remove callbacks to try to recover the device after an error on
the bus. However, these callbacks have race conditions with the internal
catastrophic error recovery functions, which will also detect the error
and this can cause the system to crash if both EEH and catas functions
try to reset the device.
This patch adds the necessary error recovery callbacks and makes sure
that the internal catastrophic error functions will not try to reset the
device in such scenarios. It also adds some calls to
pci_channel_offline() to suppress reads/writes on the bus when the slot
cannot accept I/O operations so we prevent unnecessary accesses to the
bus and speed up the device removal.

The 57840 boards come in two flavours: 2 x 20G and 4 x 10G.
To better differentiate between the two flavours, a separate device ID
was assigned to each.
The silicon default value is still the currently supported 57840 device ID
(0x168d), and since a user can damage the nvram (e.g., 'ethtool -E')
the driver will still support this device ID to allow the user to amend the
nvram back into a supported configuration.

Do RAR entry accounting correctly so that errors are reported and
promisc mode is set correctly when the number of entries exceeds
the hardware limits.
This can happen with many macvlan devices attached to the PF or
by adding many fdb entries in SR-IOV modes.
Also this includes a small refactor to fdb_add() to avoid having so
many nested if/else statements after adding a check for the number
or RAR entries.
The max entries for the PF is currently 16 we allow 15 additional
entries to account for the defined MAC.

This change makes it so the function ixgbe_dcb_get_tc_from_up will use the
num_tcs.pg_tcs to determine the starting value for determining a traffic
class based on a user priority. The main motivation for this change is to
address possible bad configurations in which more TCs worth of data are
populated then there are actual TCs. By limiting this value we can at
least make certain we are not providing a map with values that are out of
range.
As a result any user priorities that are setup in the configuration with a
traffic class mapping higher than what the hardware supports will be
reported as being on TC 0.

The recent changes to netdev_alloc_skb actually make it so that the size of
the buffer now actually has a more direct input on the truesize. So in
order to make best use of the piece of a page we are allocated I am
reducing the IXGBE_RX_HDR_SIZE to 256 so that our truesize will be reduced
by 256 bytes as well.
This should result in performance improvements since the number of uses per
page should increase from 4 to 6 in the case of a 4K page. In addition we
should see socket performance improvements due to the truesize dropping
to less than 1K for buffers less than 256 bytes.

This change makes it so that we can use the atr_sample_rate to determine if
we are capable of supporting ATR. The advantage to this approach is that it
allows us to now determine the setting of the IXGBE_FLAG_FDIR_HASH_CAPABLE
based on the queueing scheme, instead of the queueing scheme being based on
the flag.
Using this approach there are essentially 5 conditions that must be checked
prior to trying to enable ATR:
1. Is SR-IOV disabled?
2. Are the number of TCs <= 1?
3. Is RSS queueing limit greater than 1?
4. Is atr_sample_rate set?
5. Is Flow Director perfect filtering disabled?
If any of these conditions are enabled they should disable ATR filtering.
Note that in the case of conditions 1 through 4 being met we will set
things up for ATR queueing, however if test 5 fails we will still leave the
queues allocated for use by perfect filters. The reason for this is to
allow for us to switch back and forth between ntuple and ATR without
needing to reallocate the descriptor rings.

This patch does two things. First it drops the unnecessary work of
searching for enabled VFs when we first bring up the adapter and instead
just uses pci_num_vf to determine how many VFs are enabled on the adapter.
The second thing it does is drop the use of vfdev from the vf_data_storage
structure. Instead we just search the entire system for a VF that has us
as it's PF, and then if that VF is assigned we indicate that the VFs are
assigned. This allows us to still check for assigned VFs even if the
vfinfo allocation has failed, or vfinfo has been freed.

This is meant to fix a bug in which we were not checking for pre-existing
VFs if we were not setting the max_vfs value at driver load. What happens
now is that we always call ixgbe_enable_sriov and this checks for
pre-existing VFs ore requested VFs prior to deciding on no SR-IOV.

When io access mode is enabled by BOOTROM or BIOS for AR8152 v2.1,
the register can't be read/write by memory access mode.
Clearing Bit 8 of Register 0x21c could fixed the issue.

====================
This series contains updates to ixgbe.
...
Alexander Duyck (9):
ixgbe: Use VMDq offset to indicate the default pool
ixgbe: Fix memory leak when SR-IOV VFs are direct assigned
ixgbe: Drop references to deprecated pci_ DMA api and instead use
dma_ API
ixgbe: Cleanup configuration of FCoE registers
ixgbe: Merge all FCoE percpu values into a single structure
ixgbe: Make FCoE allocation and configuration closer to how rings
work
ixgbe: Correctly set SAN MAC RAR pool to default pool of PF
ixgbe: Only enable anti-spoof on VF pools
ixgbe: Enable FCoE FSO and CRC offloads based on CAPABLE instead of
ENABLED flag

Use PCI_VENDOR_ID_INTEL from pci_ids.h instead of creating its own
vendor ID #define.
