Our netstat(1) supports both -p for protocol and -f for family, while
sockstat(1) indeed only supports -f for family (and -p seems already
reserved for ports). If netstat cannot serve your need, I don't
personally see a problem in adding -P, if it's easy enough to add
without breaking existing functionality (or default behaviour without
Considering the popularity FreeBSD has, there might be more software
not directly using sysctl or ioctls and expecting such useful commands
to behave consistently across BSDs. And according to the man page's
HISTORY, although our implementation is a cleanroom one, it was
inspired from the FreeBSD command of the same name in the netbsd-3
days... So it makes sense to support -P, IMO.
