net: l2tp: Treat NET_XMIT_CN as success in l2tp_eth_dev_xmit
The tc could return NET_XMIT_CN as one congestion notification, but it does not mean the packe is lost. Other modules like ipvlan, macvlan, and others treat NET_XMIT_CN as success too. So l2tp_eth_dev_xmit should add the NET_XMIT_CN check. Signed-off-by: Gao Feng <gfree.wind@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
