Setting mq_mode for virtio to ETH_MQ_RX_NONE
As described in https://patches.dpdk.org/patch/60354/, we cannot set mq_mode for a vertio device to ETH_MQ_RX_RSS. Therefore adding this extra test before setting mq_mode. Change-Id: I8a33cf73afaa2cef8b9b012bf8ebe7296e1e692d Signed-off-by: Luc Provoost <luc.provoost@intel.com>
