From: Jesper Dangaard Brouer <bro...@redhat.com> The veth driver is a virtual device, and should not have assigned the default qdisc. Verified (ndo_start_xmit) veth_xmit can only return NETDEV_TX_OK, thus this should be safe to bypass qdisc.
Not assigning a qdisc is subtly done by setting tx_queue_len to zero.
