Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commits 612d2b4fe0a1 ("batman-adv: network coding - save
overheard and tx packets for decoding") and 2df5278b0267 ("batman-adv:
network coding - receive coded packets and decode them") from the
net-next tree interacting with commit fe8a93b95145 ("batman-adv: make
is_my_mac() check for the current mesh only") from the net tree.

I added the following merge fix patch and can carry it as necessary:
