The key arguement i make (from day one actually) is to leave the majority of the work to the driver. My view of wireless WMM etc is it is a different media behavior (compared to wired ethernet) which means a different view of strategy for when it opens the valve to allow in more packets. 802.11 media has embedded signalling which is usable. Guy Cohen gave a good use case which i responded to. Do you wanna look at that and respond? cheers, jamal - 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
