Subject: net/virtio: split Rx/Tx queue
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=01ad44fd374fb8ecb9ecc80b9bfd1f45dbaa4a1f;p=dpdk.git

net/virtio: split Rx/Tx queue

We keep a common vq structure, containing only vq related fields,
and then split others into RX, TX and control queue respectively.
