Re: [PATCH vhost 0/2] virtio_net: fix for stuck when change 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.

PS.
Hi Michael, I don't know which way is more convenient for you, so I split the
commit into two commits, so you can fixup to my previous commit:

    virtio_net: support tx queue resize
	virtio_net: support rx queue resize

Xuan Zhuo (2):
  virtio_net: fix for stuck when change rx ring size with dev down
  virtio_net: fix for stuck when change tx ring size with dev down

Which patches does this fix?
Maybe I should squash.
