Minor style issue reported by checkpatch which can be fixed after merge.
Although sizeof is actually an operator in C, it is considered correct
style to treat it as a function.
WARNING: sizeof hdr->hdr should be sizeof(hdr->hdr)

allow user to change the number of queues when the device is running on demand.

This patch adds the multiqueue (VIRTIO_NET_F_MQ) support to virtio_net
driver. VIRTIO_NET_F_MQ capable device could allow the driver to do packet
transmission and reception through multiple queue pairs and does the packet
steering to get better performance. By default, one one queue pair is used, u
To support multiqueue transmitq/receiveq, the first step is to separate queue
related structure from virtnet_info. This patch introduce send_queue and
receive_queue structure and use the pointer to them as the parameter in
functions handling sending/receiving.

Add multiqueue support to virtio network device.
Add a new feature flag VIRTIO_NET_F_MQ for this feature, a new
configuration field max_virtqueue_pairs to detect supported number of
virtqueues as well as a new command VIRTIO_NET_CTRL_MQ to program
packet steering for unidirectional protocols.
