AFAIU, Batman will never send a packet back on the same interface (be it
wired or wireless, whatever the frequency, etc. – they don’t care at all).
Except if this is the only available one, of course, or if the alternative
interfaces have been dismissed for some reason (too low quality, etc.).
They just decide upfront a set of alternative interfaces, and then choose the
best interface that it is not the incoming one among this set, for each packet.
You have no way to declare that two different wifi interfaces interfere, for
instance; it is roughly similar to babel -z1.
