[libvirt] [PATCH 0/3] exposing busy polling support for vhost-net



From: Sahid Orentino Ferdjaoui <sahid ferdjaoui redhat com>

In version 2.7.0, QEMU introduced support of busy polling for
vhost-net [0]. To avoid paraphrasing original authors of that feature
and the purpose it I prefer to share a pointer [1].

This patch serie exposes throught the NIC driver-specific element a
new option 'poll_us'. That option is only available with the backend
driver 'vhost'.

The option 'poll_us' takes a positive number. 0 means that the option
is not going to be exposed.
