>Description:
ifconfig(8) does not document new lagg(4) interface options (laggproto, (-)laggport, laggportpri).
lagg(4) reference is also missing in "SEE ALSO" section.

Deprecated agr(4) are documented, thus my assumption lagg's should be as well.

Documentation is missing in current and NetBSD-10.
>How-To-Repeat:
man ifconfig
Look for the lagg(4) options and reference.
