ALTQ, pf and VLANs

[Marko Čuk]

I am still running 5.3-RELEASE-p5 and there is

/*$FreeBSD: src/sys/dev/em/if_em.c,v 1.44.2.2 2004/10/15 22:12:59 
tackerman Exp $*/

, obviously unpatched and bad driver. I'll try to cvsup to 5.4-PRE, but 
I'm a little worried with stability, as this is my main firewall for 
whole network.

2nd thing... try to disable it manually ? What :) ? I don't quite 
understand you on that .

ifconfig em1 disable ? :)  I have traffic on it :)  ( I'll be running 
carp as soon and pfsync as I'll learn how to and if it will work fine  
:) , to have redaudant firewall )
