Description

FreeBSD 12.3 introduced a new dnctl(8) utility, which can be used to change limiter parameters without reloading filter

see https://www.freebsd.org/cgi/man.cgi?query=dnctl&sektion=8&format=html:

PIPE, QUEUE AND SCHEDULER CONFIGURATION
     The pipe, queue and scheduler configuration commands are the following:

       pipe    number config pipe-configuration

       queue number    config queue-configuration

       sched number    config sched-configuration

1) #12003 should be merged first

2) Converting ipfw -> dnctl is not that difficult, but dnctl(8) needs the "-f" option to load limiter rules ("dnctl -f /tmp/rules.limiter")

With https://gitlab.netgate.com/pfSense/FreeBSD-src/-/merge_requests/57 (a cherry pick of an upstream main commit) dnctl can read commands from files just like ipfw. That is, if the argument starts with '/' it's treated as a file. So `dnctl /foo/bar/dnctl.conf` will load commands from /foo/bar/dnctl.conf.
