commit 7e3a301b51a15597a6d1b9595263ac4212929a68 Author: Andrew Lunn andrew@lunn.ch Date: Mon May 9 20:03:36 2016 +0200
batctl: Include frame priority in fragment header
Unfragmented frames which traverse a node have their skb->priority set by looking at the IP ToS byte, or the 802.1p header. However for fragments this is not possible, only one of the fragments will contain the headers. Instead, place the priority into the fragment header and on receiving a fragment, use this information to set the skb->priority for when the fragment is forwarded.
