The branch stable/13 has been updated by melifaro: URL: https://cgit.FreeBSD.org/src/commit/?id=fe04896da3fbfc6c57154024dee090f365c8f1b1 commit fe04896da3fbfc6c57154024dee090f365c8f1b1 Author: Alexander V. Chernikov <melifaro@FreeBSD.org> AuthorDate: 2021-04-23 21:28:38 +0000 Commit: Alexander V. Chernikov <melifaro@FreeBSD.org> CommitDate: 2021-04-26 08:49:14 +0000 Improve debugging output on routing tests failure. Most of the routing tests create per-test VNET, making it harder to repeat the failure with CLI tools. Provide an additional route/nexthop data on failure.
