I think it's actually a substantial lose, since all that will happen is that the VLAN code will spin for a cycle or two to locate the correct pseudo-interface and then stick the decapsulated packet on a different soft ISR's queue instead. Better to decapsulate immediately and avoid an extra queueing step. -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
