The branch stable/13 has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=7cbb184bbfa3ffab031aca864647ddb387094e27 commit 7cbb184bbfa3ffab031aca864647ddb387094e27 Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2025-08-27 15:55:22 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2025-10-04 16:43:21 +0000 gif.4: Mention that gif(4) can tunnel Ethernet traffic Ideally this manpage shall have examples for the EtherIP setup, but there has been one in if_bridge(4) since the introduction of EtherIP [1], so direct the setup to if_bridge(4) at this moment. While here, add RFC 3378 to the reference section.
