[net-next 01/10] ixgbe: SR-IOV: dynamic IEEE DCBx default priority changes

[Jeff Kirsher]

From: John Fastabend <john.r.fastabend@intel.com>

IEEE DCBx has a mechanism to change the default user priority. In
the normal case the OS can handle this via cgroups, iptables, socket,
options etc.

With SR-IOV and direct assigned VF devices the default priority
needs to be set by the PF device so the inserted VLAN tag is
correct.

[net-next 02/10] ixgbe: Make TSO check for CHECKSUM_PARTIAL to avoid skb_is_gso check

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

This change is meant to reduce the overhead for workloads that are not
using either TSO or checksum offloads.  Most of the time the compiler
should jump ahead after failing this check to the VLAN check since in the
ixgbe_tx_csum call we start with that check as well.

[net-next 03/10] ixgbe: Always use context 0, even for FCoE and TSO

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

We were spending cycles separating the FCoE and TSO contexts even though we
always overwriting the context anyway.  Instead of doing that we can just
use context 0 for all descriptors.

[net-next 04/10] ixgbe: Update ixgbe Tx flags to improve code efficiency

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

This change is meant to improve the efficiency of the Tx flags in ixgbe by
aligning them with the values that will later be written into either the
cmd_type or olinfo.  By doing this we are able to reduce most of these
functions to either just a simple shift followed by an or in the case of
cmd_type, or an and followed by an or in the case of olinfo.

To do this I also needed to change the logic and/or drop some flags.  I
dropped the IXGBE_TX_FLAGS_FSO and it was replaced by IXGBE_TX_FLAGS_TSO since
the only place it was ever checked was in conjunction with IXGBE_TX_FLAGS_TSO.
I replaced IXGBE_TX_FLAGS_TXSW with IXGBE_TX_FLAGS_CC, this way we have a
clear point for what the flag is meant to do.  Finally the
IXGBE_TX_FLAGS_NO_IFCS was dropped since were are already carrying the data
for that flag in the skb.  Instead we can just check the bitflag in the skb.

In order to avoid type conversion errors I also adjusted the locations
where we were switching between CPU and little endian.

[net-next 05/10] ixgbe: Improve performance and reduce size of ixgbe_tx_map

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

This change is meant to both improve the performance and reduce the size of
ixgbe_tx_map.  To do this I have expanded the work done in the main loop by
pushing first into tx_buffer.  This allows us to pull in the dma_mapping_error
check, the tx_buffer value assignment, and the initial DMA value assignment to
the Tx descriptor.  The net result is that the function reduces in size by a
little over a 100 bytes and is about 1% or 2% faster.

[net-next 06/10] ixgbevf: Synch out of tree and in tree mailbox interrupt handlers

[Jeff Kirsher]

From: Greg Rose <gregory.v.rose@intel.com>

The out of tree driver and the in kernel driver should use the same
interrupt handling logic for mailbox interrupts.  The difference in
the handlers was causing dissimilar behavior between the two drivers
complicating debug and trouble shooting.

[net-next 08/10] ixgbevf: Fix statistics corruption

[Jeff Kirsher]

From: Greg Rose <gregory.v.rose@intel.com>

When the physical function (PF) is reset for any reason the statistics
collection in ixgbevf_update_stats needs to wait to update until after
the reset synchronization ensures that the PF driver is up and running
and is finished with its own reset.  Go ahead and clear the link flag to
indicate this when the control message from the PF is received.  The
reset synchronization and recovery in the watchdog task will eventually
set the link flag up when the PF has resumed.

The rmb in the Tx cleanup path is a much stronger barrier than we really need.
All that is really needed is a read_barrier_depends since the location of the
