[B.A.T.M.A.N.] [PATCH] openwrt-feed-batman-adv: enable batadv_vlan protocol

[Antonio Quartulli <antonio@meshcoding.com>]

From: Antonio Quartulli <antonio@open-mesh.com>

This protocol can be used to change VLAN-specific settings
of a batman-adv soft-interface.
At the moment only ap_isolation is available, but new ones
can be easily added as soon as batman-adv get to support more.

Interface configuration example:

config interface 'bat0vlan1'
	option protocol 'batadv_vlan'
	option ifname 'bat0.1'
	option ap_isolation '1'

**this patch has been tested only with the stable package in openwrt-routing**
