    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.
