The branch main has been updated by kbowling: URL: https://cgit.FreeBSD.org/src/commit/?id=8eeb25899afd7818d99ce1500be27ae8d992131f commit 8eeb25899afd7818d99ce1500be27ae8d992131f Author: Kevin Bowling <kbowling@FreeBSD.org> AuthorDate: 2026-08-08 11:10:41 +0000 Commit: Kevin Bowling <kbowling@FreeBSD.org> CommitDate: 2026-08-08 12:00:44 +0000 ixv: Remove unused loader tunables The flow_control and hdr_split variables have never been read. VF flow control is controlled by the PF, while implementing header split would require receive-path support that ixv does not provide.
