The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=1eb727727a9acb5f1e66e3f70b0146e7c9c5f710 commit 1eb727727a9acb5f1e66e3f70b0146e7c9c5f710 Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2026-02-17 19:03:35 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2026-02-17 20:22:05 +0000 ndp tests: Fix flakiness in ndp_slaac_default_route The test sends RAs in order to test SLAAC handling in another host. The router needs to also set net.inet6.ip6.forwarding=1, otherwise NAs sent from it have the ROUTER flag clear, and upon receiving such an NA the host will automatically delete routes learned from the router.
