>Description:
`service npf status` does nothing.
it would be nice if it did.

for example, npfctl show is a good candidate for this.
perhaps too verbose? it is possible to only show filtering status, with changes to npfctl.

example output:
# npfctl show
# filtering:    inactive
# config:       loaded

# service npf start
Enabling NPF.
# npfctl show
# filtering:    active
# config:       loaded

map re0 dynamic any -> 10.0.0.3 pass family inet4 from 192.168.0.1/16 

group "external" on re0 
        pass stateful out final all 

group "internal" on re1 
        pass in final family inet4 from 192.168.0.1/24 
        pass out final all 

group 
        pass final on lo0 all 
        block all
