The branch main has been updated by kp: URL: https://cgit.FreeBSD.org/src/commit/?id=cd46399b9ccf04f6ec00a532e52c8b1edb007af7 commit cd46399b9ccf04f6ec00a532e52c8b1edb007af7 Author: Kristof Provost <kp@FreeBSD.org> AuthorDate: 2021-08-26 08:25:57 +0000 Commit: Kristof Provost <kp@FreeBSD.org> CommitDate: 2021-08-26 09:23:39 +0000 pf tests: ALTQ priority test Test that ALTQ can prioritise one type of traffic over another. Do this by establishing a slow link and saturating it with ICMP echos. When prioritised TCP connections reliably go through. When not prioritised TCP connections reliably fail.
