This issue is caused by commit "7b0411ef4aa69c9256d6a2c289d0a2b320414633"
After this patch, during `virtnet_poll`, function `virtnet_poll_cleantx`
will be invoked, which will wakeup tx queue and clear queue state.
If you agree with it, I will repost with this Fixes tag later.

Fixes: 7b0411ef4aa6 ("virtio-net: clean tx descriptors from rx napi")
