The following commit has been merged in the master branch: commit c33705188c493b7de3b8dc2956d67de91b444727 Author: Gao Feng gfree.wind@gmail.com Date: Mon Nov 21 23:00:32 2016 +0800

batman-adv: Treat NET_XMIT_CN as transmit successfully

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 handle NET_XMIT_CN also as NET_XMIT_SUCCESS.
