The branch stable/14 has been updated by emaste: URL: https://cgit.FreeBSD.org/src/commit/?id=d776dd5fbd484acdf00f6df55583e9aa53226859 commit d776dd5fbd484acdf00f6df55583e9aa53226859 Author: Denny Page <dennypage@me.com> AuthorDate: 2024-04-13 17:16:08 +0000 Commit: Ed Maste <emaste@FreeBSD.org> CommitDate: 2024-04-27 14:45:22 +0000 Support ARP for 802 networks This is used by 802.3 Ethernet. (Also be used by 802.4 Token Bus and 802.5 Token Ring, but we don't support those.) This was accidentally removed along with FDDI support in commit 0437c8e3b198, presumably because comments implied it was used only by FDDI or Token Ring. Fixes: 0437c8e3b198 ("Remove support for FDDI networks.")
