From c54f38c9aa22ff65ca9f4c1bdbf2a11d017205f3 Mon Sep 17 00:00:00 2001 From: Simon Wunderlich Date: Mon, 29 Jul 2013 17:56:44 +0200 Subject: batman-adv: set skb priority according to content The skb priority field may help the wireless driver to choose the right queue (e.g. WMM queues). This should be set in batman-adv, as this information is only available here. This patch adds support for IPv4/IPv6 DS fields and VLAN PCP. Note that only VLAN PCP is used if a VLAN header is present. Also initially set TC_PRIO_CONTROL only for self-generated packets, and keep the priority set by higher layers.

This fix the Bridge Loop Avoidance behaviour which was not able to send announces over VLAN interfaces.
