The branch main has been updated by kbowling: URL: https://cgit.FreeBSD.org/src/commit/?id=5e05c40aff53f2adb366b3c30ff5b98aac0bb54a commit 5e05c40aff53f2adb366b3c30ff5b98aac0bb54a Author: Kevin Bowling <kbowling@FreeBSD.org> AuthorDate: 2026-07-31 12:58:30 +0000 Commit: Kevin Bowling <kbowling@FreeBSD.org> CommitDate: 2026-08-06 11:23:41 +0000 ixv: defer every admin-vector interrupt The VF admin vector carries both link and PF mailbox causes, but the filter schedules the admin task only for link-status changes. Defer administration for every interrupt so reset and control notifications are serviced promptly.
