Subject: [PATCH 078/145] ixgbevf: VF2VF TCP RSS |
| 5 |
|
| 6 |
[ Upstream commit 7fb94bd58dd6650a0158e68d414e185077d8b57a ] |
| 7 |
|
| 8 |
While VF2VF with RSS communication, RSS Type were wrongly recognized |
| 9 |
and RSS hash was not calculated as it should be. Packets was |
| 10 |
distributed on various queues by accident. |
| 11 |
This commit fixes that behaviour and causes proper RSS Type recognition. |
