Hello...

I have really big problems with the latest trunk on my madwifi AP. It somehow works but the multicastqueue fills up over the time and never empties => NETDEV Watchdog barks a lot and all clients drop connection... rendering the AP unuseable.

What happend? the bug sneaked in... as the old trunk-r3640 still works great.
