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.

Instead of all of this churn, just change the dev_queue_xmit() call in
net/batman-adv/send.c to be:

	return net_xmit_eval(dev_queue_xmit(skb));
