Hope this can still make it. I was not sure about virtio-net change but it seems that it prevents livelocks for some people. The following changes since commit 089cf7f6ecb266b6a4164919a2e69bd2f938374a: Linux 5.3-rc7 (2019-09-02 09:57:40 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git tags/for_linus for you to fetch changes up to

From: Tonghao Zhang <xiangxia.m.yue at gmail.com> Factor out generic busy polling logic and will be used for in tx path in the next patch. And with the patch, qemu can set differently the busyloop_timeout for rx queue. In the handle_tx, the busypoll will vhost_net_disable/enable_vq because we have poll the sock. This can improve performance. [This is suggested by Toshiaki Makita
