wireshark. It is very simply, when the client receive a ping request ifenslave
answer it one time on eth0 and the next on wlan0. Then brctl learn which is the
interface to forward the data.

Two interfaces should never have same port number (at least as far as bridge is
concerned).

Port number only matters to STP, which you probably are not using.

Two active interfaces on same network with bridge is equivalent to forwarding
loop. You need to run STP, and have only one active interface.

What do you think that it is the best way of doing it??

Yes you can go do what you want with the code, but this is really one
of those: "I think I can hack the bridge code to do my own personal
idea of special case routing"
My answer to this is: "have fun, tell us what you find out, don't
expect any support"
