know.
------------------
From: Antonio Quartulli <anto...@open-mesh.com>
[ Upstream commit cc2f33860cea0e48ebec096130bd0f7c4bf6e0bc ]
Change introduced by 88e48d7b3340ef07b108eb8a8b3813dd093cc7f7
("batman-adv: make DAT drop ARP requests targeting local clients")
implements a check that prevents DAT from using the caching
mechanism when the client that is supposed to provide a reply
to an arp request is local.
However change brought by be1db4f6615b5e6156c807ea8985171c215c2d57
("batman-adv: make the Distributed ARP Table vlan aware")
has not converted the above check into its vlan aware version
thus making it useless when the local client is behind a vlan.
Fix the behaviour by properly specifying the vlan when
checking for a client being local or not.
