Can batman operate on top of a vlan? For example, a wireless link with MTU of 1532 to accommodate both batman and the vlan. Plugs into the batman-adv box on eth0, configure eth0.10 and add eth0.10 to bat0.
This is meant to solve a specific issue of needing non-batman-adv access to the radio web-ui's on the native/untagged vlan1
thanks.

It should work. batman-adv is not too picky about what is used below it. It must be able to transport ethernet frames and it must allow things like broadcasts. We could go here into more details but it wouldn't help us to answer the question. At least 802.1Q should not influence the behavior in any significant way and should therefore not be a problem.
Kind regards, Sven
thanks. Just to clarify, batman-adv 32 bytes, so to stack vlans qinq I need 32+4+4 so 1540 yes?

Seems to be right.
But TT doesn't track QinQ clients with two VLANs (it only tracks the outer VLAN). Maybe Antonio already thought about possible consequences.

I haven't really thought this trough, but I think it should still work, because batman-adv will just take care of delivering the packet to/from where the outer encapsulation is applied/removed. What happens to the inner payload should not be batman's business. If I see this correctly.
