Hi,

I've never programmed anyting connected with wireless. But I remember an 
issu that came up with wireless and bridge code. IIRC the problem was 
that wireless IF are not capable of receiving packets with an unknown 
MAC, but bridge code changes the sender MAC. I solved this problem by 
setting up a tunnel between 2 wireless IF and the bridge code used the 2 
tunnel endpoints.

What I want to say is that I think there is now difference in tcpip, but 
in the arp handling.
