Subject: [PATCH] virtio_net: return error when there is no virtqueue or MQ isn't support
Date: Mon, 21 Apr 2014 23:11:01 +0800 [thread overview]
Message-ID: <1398093061-13444-1-git-send-email-akong@redhat.com> (raw)
Currently ethtool returns zero if there is no virtqueue or MQ isn't
support, we should return -ENOTSUPP to notice user.
