From: Ani Sinha <anisi...@redhat.com>An assertion was missing for tap vhost backends that enforces a non-null reference from get_vhost_net(). Both vhost-net-user and vhost-net-vdpa enforces this.

A system of mine without vhost_net (old host kernel) is reaching this assert and works perfectly fine without. Should it be considered as a regression ? Thanks, C.
