It's a bugfix, not a feature, and the bug is very specific to 2.2 because there is no bridging yet in 3.0, thus i doubt the problem can occur. So i figured out it was more urgent to fix 2.2 as soon as i can get my 3.0 machine up i will patch that as well. cheers 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 cvs-all" in the body of the message
