Subject: virtio: fix tx_ stats in virtio_net
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=655aa31f028c4498e8896576571ee1ea68dd26e0;p=openwrt%2Fstaging%2Fblogic.git

virtio: fix tx_ stats in virtio_net

get_buf() gives the length written by the other side, which will be
zero.  We want to add the skb length.
