Subject: batman-adv: fix vlan header access
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2b1e2cb3594df80446dc33bb8e12230da11f38ff;p=openwrt%2Fstaging%2Fblogic.git

batman-adv: fix vlan header access

When batadv_get_vid() is invoked in interface_rx() the
batman-adv header has already been removed, therefore
the header_len argument has to be 0.

Introduced by c018ad3de61a1dc4194879a53e5559e094aa7b1a
("batman-adv: add the VLAN ID attribute to the TT entry")
