febc61d350 net/i40e: optimize flow director update rate
This patch optimized the fdir update rate for i40e PF, by tracking
whether the fdir rule being inserted into the guaranteed space
or shared space.
For the flows that are inserted to the guaranteed space, we assume
that the insertion will always succeed as the hardware only report
the "no enough space left" error. In this case, the software can
directly return success and no need to retrieve the result from
the hardware. When destroying a flow, we also assume the operation
will succeed as the software has checked the flow is indeed in
the hardware.
See the fdir programming status descriptor format in the datasheet
for more details.

cc46d3d368 net/i40e: support flow director on SSE Rx
This commit adds an implementation to the SSE vector implementation of
RX routine and moves some common defines from a c file to the header
file.

I40e can have 16 and 32 byte descriptors, and the Flow
Director ID data and indication-bit are in different locations
for each size descriptor. The support is implemented in two
separate functions as they require vastly different operations.

The 16B descriptor re-purposes the "filter-status" u32 field
to indicate FDIR ID when the FLM bit is set. No extra loads
are required, however we do have to store to mbuf->fdir.hi,
which is not stored to in the RX path before this patch.

The 32B descriptor requires loading the 2nd 16 bytes of each
descriptor, to get the FLEXBH_STAT and FD Filter ID from
qword3. The resulting data must also be stored to mbuf->fdir.hi,
same as the 16B code path.

6ae9b2b5e8 net/i40e: cache flow director enable value in Rx queue
This commit adds a fdir_enable flag in a uint8_t sized hole
the rx queue structure The flag enables the rx code path to
easily identify if fdir is active. This can be used to skip
fdir id processing when it is not required.

The flag is zero by default (as rxq is zmalloc-ed at startup),
and the flag is set to 1 on configuration of a flow director rule.

d0510c2a25 i40e: fix alignment of HW descriptors number
According to XL710 datasheet:
RX QLEN restrictions: When the PXE_MODE flag in the GLLAN_RCTL_0
register is cleared, the QLEN must be whole number of 32
descriptors.
TX QLEN restrictions: When the PXE_MODE flag in the GLLAN_RCTL_0
register is cleared, the QLEN must be whole number of 32
descriptors.

So make sure that for both RX and TX queues number of HW descriptors is
a multiple of 32.
