Please help me to understand why that is a problem.

I don’t know if you can understand what I said. My English is not so good.
Sorry, I still don't really get it. You say a frame is being sent to the
bridge (tcpip_input) that you want to get sent out to ports instead.
Which frame is this? I.e. which DST MAC does it have?
Normally, 'bridgeif_is_local_mac()' should only return 1 for local MAC
addresses of the bridge or its ports (if they have any at all). This is
by design of a (managed) switch. You cannot use a port's MAC address to
get the bridge to send out on a selected port. That's not the way
bridges work, if that's what you're trying?
Are you sure you're looking for a bridge? In the end, this bridge just
mimics a hardware switch.
