The branch stable/12 has been updated by 0mp (doc, ports committer): URL: https://cgit.FreeBSD.org/src/commit/?id=1bd6c85cf125bf9256ec4fab77dcf8c42badbda8 commit 1bd6c85cf125bf9256ec4fab77dcf8c42badbda8 Author: Mateusz Piotrowski <0mp@FreeBSD.org> AuthorDate: 2022-03-29 11:11:46 +0000 Commit: Mateusz Piotrowski <0mp@FreeBSD.org> CommitDate: 2022-04-12 14:36:13 +0000 ifconfig.8: Add capability codes descriptions from handbook We document capability codes (the CAPS field of "ifconfig wlan0 scan") in both ifconfig(8) and the handbook. The list is more complete in the manual page, while the descriptions of individual capabilities are more detailed in the handbook. In order to reduce content duplication and bit rot, let's move handbook's details to the manual page and reference the manual page whenever necessary.
