Until the time a more robust versioning scheme is needed/implemented all
established virtual channel opcode values should remain consistent between
updates to the opcode enum.
This patch repositions I40E_VIRTCHNL_OP_CONFIG_RSS to the end of the enum. In
its current position this opcode displaces the initial value of
I40E_VIRTCHNL_OP_EVENT and will cause PF/VF compatibility issues.
Going forward the expectation is either:
a) All future opcode additions will be added as the last element of the
enum. Once VF drivers start making use of the new commands the virtual
channel version will need to be incremented and drivers will need to
implement a simple version check whereby VF drivers can only load on
PFs with a >= version.
b) or, if needed, design and implement a more complicated API
negotiation capability.
In either case PF drivers should always maintain backwards compatibility with
earlier VF driver versions.

Split the receive hot path code into two, one for packet split and one
for single buffer. This improves receive performance since we only need
to check if the ring is in packet split mode once per NAPI poll time,
not several times per packet. The single buffer code is further improved
by the removal of a bunch of code and several variables that are not
needed. On a receive-oriented test this can improve single-threaded
throughput.
Also refactor the packet split receive path to use a fixed buffer for
headers, like ixgbe does. This vastly reduces the number of DMA mappings
and unmappings we need to do, allowing for much better performance in
the presence of an IOMMU.
Lastly, correct packet split descriptor types now that we are actually
using them.

Currently rs uses the info in mac80211 tx status which is
a translation of the actual rate coming up from the FW in
the tx response. This is matched up against the LQ table first
rate to make sure this tx frame used the current LQ table.
Instead of using the translated mac80211 info it's easier and
cleaner to just pass the actual tx response rate in the driver
private data and use that for matching.
This becomes even more important once the FW begins to
decide on its own whether to use STBC/BFER/SISO.

fail for other reasons, such as a timeout. In such cases, we should
