Subject: [PATCH net-next 1/2] net: batman-adv: Treat NET_XMIT_CN as transmit successfully
From: Gao Feng <gfree.wind@...il.com>
The tc could return NET_XMIT_CN as one congestion notification, but
it does not mean the packet is lost. Other modules like ipvlan,
macvlan, and others treat NET_XMIT_CN as success too.
So batman-adv should add the NET_XMIT_CN check.
