[ Upstream commit 7fb94bd58dd6650a0158e68d414e185077d8b57a ]

While VF2VF with RSS communication, RSS Type were wrongly recognized
and RSS hash was not calculated as it should be. Packets was
distributed on various queues by accident.
This commit fixes that behaviour and causes proper RSS Type recognition.
