Just to clarify my point of view: the things we would need to clarify are:
a) how can we detect the RX port when a pbuf is received in lwIP (i.e. 
on the 9th port) and
b) how can we tell the bridge/switch to auto-select (1 or more) target 
port(s) or send to (one or more) specific port(s)

The rest is an implementation detail of the bridge/switch. Which might 
be implemented in software or possibly in a real switch IC.
I'm not opposed to sharing such a software implementation, but as I said 
before, I only see the 2 points above as belonging into
"core" lwIP. The software implementation of a bridge/switch is "just 
another netif driver"...
