virtio_net: support rx queue resize
This patch implements the resize function of the rx queues.
Based on this function, it is possible to modify the ring num of the
queue.
Includes fixup:
virtio_net: fix for stuck when change rx ring size with dev down
When dev is set to DOWN state, napi has been disabled, if we modify the
ring size at this time, we should not call napi_disable() again, which
will cause stuck.
And all operations are under the protection of rtnl_lock, so there is no
need to consider concurrency issues.
