The problem with layer 2 tricks is that the classifier needs to parse multiple link headers (e.g., PPPoE) to look at the IP header. In the new ALTQ design, the classifier hook and the scheduler hook are separated so that the classifier can be called before prepending link headers. But it might need another trick to pass the classifier result to the enqueue operation if the classifier hook and the enqueue operation can't be placed in the same function. (one possible solution is to tag the result to mbuf itself but this is going to be a seperate project.) -Kenjiro To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
