#1612289 — [PATCH net-next] virtio_net: don't reset twice on XDP on/off

From"Michael S. Tsirkin" <mst@redhat.com>

Subject[PATCH net-next] virtio_net: don't reset twice on XDP on/off
Message-ID<tqseu-3C5-23@gated-at.bofh.it>
We already do a reset once in remove_vq_common -
there appears to be no point in doing another one
when we add/remove XDP.
