o Make ipfw(8) show rules with mac/mac-type options correctly.

Browse Source 
Before:

$ ipfw -n add 100 count icmp from any to any mac-type 0x01
00100 count icmp 0x0001
$ ipfw -n add 100 count icmp from any to any mac any any
00100 count icmp MAC any any any

After:

$ ipfw -n add 100 count icmp from any to any mac-type 0x01
00100 count icmp from any to any mac-type 0x0001
$ ipfw -n add 100 count icmp from any to any mac any any
00100 count icmp from any to any MAC any any
