As seen on the dump, you only use eth0 in batman? Is the Ad-Hoc connection
still active (on wlan0 or wlan-1)?

Mhm, that's weird indeed. Is eth0 really not included in any other bridge?
It looks like the incoming packets don't reach BATMAN for some reason.

Also have you checked that the WDS bridge works via IP? You could first set
up some IP addresses and ping each other, confirm traffic with tcpdump, and
then activate batman-adv to see if the OGMs go through. So far, it  doesn't
seem like anything from your C node comes through at all.

Cheers,
