There are a lot of rules that we're certain but "chains" can be emulated with relative ease and efficiency using optimized SKIPTO instructions. Possibly we can have a 'switch' type of instruction to speed up initial selections basing on source/dst interface, or protocol types (small sets, in any case). I am a bit reluctant on using pre-defined chains. it looks too high level, and i cannot tell very well if the mechanism is too strict, useful or overkill. luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
