The branch stable/13 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=1a305490732cdd30d19627b49847ebe09009a8f7 commit 1a305490732cdd30d19627b49847ebe09009a8f7 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2021-12-13 22:10:25 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2021-12-29 16:01:46 +0000 rc: network.subr improve network6_getladdr() In network6_getladdr() we are iterating over inet6 lines and are not interested in any others. So tell ifconfig to limit output to "inet6" as much as possible. This is probably a micro-optimisation but was noticed while looking at other IPv6-related boot-time improvements.
