Hi,All I'd like to implement the function of "recognize and schedule traffic that makes use of the P bit as defined in IEEE 802.1P" by iproute2/tc in mips linux device.I think I should use iptables or u32 filter to recognize P bits of traffic and then put them into different queues(classes).But how to do this filter function by iptables or u32? Any suggestion is highly appreciated!Thanks. Best regards. swcims swcims@xxxxxxx 2004-06-21 ???????????????????ē?%?,S????醑?m??ē????????-?棹V?廖Y3???????
