From 9e2e7efbbbff69d8340abb56d375dd79d1f5770f Mon Sep 17 00:00:00 2001 From: Johnathan Mantey Date: Mon, 13 Nov 2023 08:30:29 -0800 Subject: Revert ncsi: Propagate carrier gain/loss events to the NCSI controller This reverts commit 3780bb29311eccb7a1c9641032a112eed237f7e3. The cited commit introduced unwanted behavior. The intent for the commit was to be able to detect carrier loss/gain for just the NIC connected to the BMC. The unwanted effect is a carrier loss for auxiliary paths also causes the BMC to lose carrier. The BMC never regains carrier despite the secondary NIC regaining a link. This change, when merged, needs to be backported to stable kernels. 5.4-stable, 5.10-stable, 5.15-stable, 6.1-stable, 6.5-stable Fixes: 3780bb29311e ("ncsi: Propagate carrier gain/loss events to the NCSI controller") CC: stable@vger.kernel.org Signed-off-by: Johnathan Mantey Reviewed-by: Simon Horman Signed-off-by: David S.
