 This was on an amd64, NetBSD 8.0_BETA as of Sat Sep  9 12:02:11 AEST 2017.
 
 It's pretty easy to dump out the bytecode:
 
 slave:ksh$ cat /tmp/npf.conf 
 group "fubar" on wi0 {
         pass in final proto tcp to any port { 1, 4-5, 7 }
         pass in final proto tcp to any port { 4-5, 7 }
         pass in final proto tcp to any port { 1, 4-5 }
         pass in final proto tcp to any port { 4-5 }
 }
 slave:ksh$ npfctl debug /tmp/npf.conf /tmp/zz
 npfctl: warning - unknown interface 'wi0'
 npfctl: default group was not defined

 I'm building -current, and I'll double check its behaviour when I get it
 installed somewhere.
