I've been working on getting your new fwcontrol to compile and run
on NetBSD.  Looks like FreeBSD used to use /dev/fw0.0 but now
uses fw0, which...is...a symlink to fw0.0.  I only have .0 no .[123]
NetBSD still uses fw0.0, MAKEDEV doesn't create the symlink.  So now
you know why I noticed that fwcontrol doesn't tell you what filename
it couldn't open.  :-)  Still no idea what the trailing digit is for,
or why the fwcontrol code was changed.
