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.
