How to get pf to wait for ng0

[Sam Fourman Jr.]

Hello list,

I am trying to use FreeBSD 8 RC1 to setup L2 tunnels via mpd5.
My problem is the pf.conf file is never parsed because ng0 does not
exist yet on startup

ng0 is this case is DSL PPPoE to our local telco for internet access.
after the DSL dials up (via mpd5) if I do pfctl -d && pfctl -e -f
/etc/pf.conf everything works as expected.

What is the best way to get pf to wait and parse the ruleset until
after ng0 exists?
