[dpdk-dev] [PATCH 1/2] igb/ixgbe: ETH_MQ_RX_NONE should disable RSS

[Maxime Leroy <maxime.leroy@6wind.com>]

As explained in rte_ethdev.h, ETH_MQ_RX_NONE allows to not choose RSS, DCB
or VMDQ mode to select the rx queues.

But the igb/ixgbe code always select RSS mode with ETH_MQ_RX_NONE. This patch
fixes this incoherence between the api and the source code.
