Thanks, CWmin is a setting that controls the random delay before packets are transmitted. Search for tqi_cwmin in the driver. The retry limit says how many times the MAC should retry if it gets a collision while trying to transmit - I think it is controled by the tqi_shretry and tqi_lgretry values. In the driver in 6.X you can (in principle) set these values at the time the transmit queues are configured. David.
