Let's just do a final review of what's going on with that code path before we commit it. > The thing is this: > > ifconfig wlan0 txpower controls global txpower.

But I want to control broadcast message Right. So this is where things get a bit "special". Is this global or per-vap? Ie, do you want to be able to set the TX power for multicast and beacon traffic per-VAP or just per-interface? I think I'm at the point where I'd better just implement per-packet TPC on the 11n chips so we at least have something to test with. Adrian
