Sounds like a fix people may want to backport. Could you repost with 
an appropriate Fixes tag added, pointing to the earliest commit where
the problem can be observed?

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")
