The Wi-Fi alliance's test plans for their WMM specification are written assuming you use certain specific DSCP values. Since WMM is the only QoS mechanism that is widely used with 802.11 I followed the WMM values in the default 802.11 qdisc implementation. Most windows 802.11 drivers do the same thing.

It wouldn't really hurt though since all frames queued to a band already have the same priority, so pfifo_fast behaves similar to fifo. BTW, is there a specific reason for using DSCP? Normally Linux uses rt_tos2priority and prio2band for determining a priority for IP packets. I don't want to argue that one is better than the other, but there is some value in keeping things consistent .. - 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
