What about using AF_PACKET bound to underlying wireless device and the
packet type. You can even use BPF to filter.

As far as I know, AF_PACKET only works when not binding it to the packet
type (otherwise it get stolen by the rx handler).

You can do AF_PACKET and it gets handle before rx_handler.

Not binding it to the packet type and using BPF to filter is expensive
on small embedded devices with small caches. Still, this requires
userspace changes, so we need a different solution.

Another alternative would be to have bridge accept control frames on
dormant device but not send.

Sounds good, will you send a patch for that?
