>Description:
After adding "npf=YES" to /etc/rc.conf and rebooting, NPF is not loaded nor active:

===
# npfctl show
Filtering:      inactive
Configuration:  empty
===

But it should be loaded and active.
>How-To-Repeat:
1. Create a super simple /etc/npf.conf containing the following:

===
group (default) {
  pass final all
}
===

2. Add "npf=YES" to /etc/rc.conf.

3. Reboot: "shutdown -r now".

4. Check the status of NPF:

===
# npfctl show
Filtering:      inactive
Configuration:  empty
===
>Fix:
I don't have a fix, but I do have a workaround.  I'm wondering if somehow the
npf kernel module is erroneously getting automatically unloaded.  My workaround is to add the following to /etc/rc.local:

===
/sbin/modunload npf
/sbin/modload npf
/sbin/npfctl reload
/sbin/npfctl start
===

Now, after booting, NPF is loaded and active:

===
# npfctl show
Filtering:      active
Configuration:  loaded



group (default) {
        pass final all 
}
===

State-Changed-Why:
Fixed in netbsd-8.  There was something broken with auto-unloading, IIRC.
Unlikely that the module changes will get pulled up to netbsd-6, though..
