The branch main has been updated by karels: URL: https://cgit.FreeBSD.org/src/commit/?id=12bd931d8c64ad2d5e78c7ab917efbff326152ca commit 12bd931d8c64ad2d5e78c7ab917efbff326152ca Author: Mike Karels <karels@FreeBSD.org> AuthorDate: 2021-10-27 03:25:09 +0000 Commit: Mike Karels <karels@FreeBSD.org> CommitDate: 2021-11-09 15:33:23 +0000 man pages: deprecate Internet Class A/B/C Mark functions inet_netof(), inet_lnaof(), and inet_makeaddr() as deprecated, as they assume Class A/B/C. inet_makeaddr() mostly works when networks are a multiple of 8 bits, but warn for anything other than historical classes. Reduce other mentions of network classes.
