Devicescape does understant that the hardware can do retries - but it adds software retries on top. This allows higher reliability, as well as correct handling of the powersave state machine. (PS bit from a STA is supposed to stop APs transmission immediately).

It does ratecontrol based on that. Basically: No ACK == failed packet. If too many failures, lower the rate. -- Greetings Michael. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
