[net-next 02/13] ixgbevf: VF2VF TCP RSS

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Sebastian Basierski <sebastianx.basierski@intel.com>

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.
