The branch main has been updated by kbowling: URL: https://cgit.FreeBSD.org/src/commit/?id=545779a99290b7b7d94dece6c096ce230be91ff9 commit 545779a99290b7b7d94dece6c096ce230be91ff9 Author: Kevin Bowling <kbowling@FreeBSD.org> AuthorDate: 2026-08-06 08:21:35 +0000 Commit: Kevin Bowling <kbowling@FreeBSD.org> CommitDate: 2026-08-07 14:01:43 +0000 ixgbe: Re-enable the SFP laser during initialization ixgbe_if_stop() disables the transmit laser on every 82599 SFP fiber port, but the iflib initialization path did not re-enable it. Re-enable the laser before deferred SFP module setup so interface reinitialization cannot leave either single-speed or multispeed optics dark. The hardware wrapper is a no-op when laser control is unavailable. The placement follows Intel ix-3.4.39; this version deliberately applies to every SFP port affected by the stop path.
