I'm testing out a setup in my lab but am having trouble configuring it correctly! I've tried a lot of variations of the setup, read the documentation, and went through the mailing list to see what I'm doing wrong, but can't figure it out.
I followed the sophisticated setup and added ethernet links to it, possibly in a wrong way. I read somewhere that ethernet interfaces must be added to batman as bridges. (Side note: this causes my dmesg output to complain about too small of MTU for the ethernet interfaces but I can't seem to raise the bridge MTU to 1528 like it suggests.)

Looking at the originator tables I see now that indeed all nodes see each other on layer 2, but I'm unable to ping the other nodes on layer 3 except between banksy and roa.
Devices roa and banksy are NanoStation M2s, and skewville and veng are WNDR3700v2s.
