[dpdk-dev] [PATCH v2] drivers/net: do not enforce RSS hash offload

[Alexander Kozyrev]

From: Alexander Kozyrev <akozyrev at mellanox.com>

Rx RSS hash offload should be controlled by the user
and should not be enforced by RSS multi-queue Rx mode.

Fixes: 8b945a7f7dcb ("drivers/net: update Rx RSS hash offload capabilities")
