I haven't used wireless with Linux yet, but you can get the bridge to
act like a hub by using these commands:
#brctl stp br0 off
#brctl setageing br0 0
#brctl setfd br0 0
That should make all packets from ms1 be forwarded to eth0. Letting all
packets with source-mac AA go from eth0 to ms1:
ebtables -A FORWARD -i eth0 -o ms1 -s $AA -j ACCEPT
ebtables -A FORWARD -i eth0 -o ms1 -j DROP

You won't need an IP address.
