This is a note to let you know that I've just added the patch titled Revert ncsi: Propagate carrier gain/loss events to the NCSI controller to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: revert-ncsi-propagate-carrier-gain-loss-events-to-the-ncsi-controller.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 9e2e7efbbbff69d8340abb56d375dd79d1f5770f Mon Sep 17 00:00:00 2001 From: Johnathan Mantey <johnathanx.mantey@xxxxxxxxx> Date: Mon, 13 Nov 2023 08:30:29 -0800 Subject: Revert ncsi: Propagate carrier gain/loss events to the NCSI controller From: Johnathan Mantey <johnathanx.mantey@xxxxxxxxx> commit 9e2e7efbbbff69d8340abb56d375dd79d1f5770f upstream. 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@xxxxxxxxxxxxxxx Signed-off-by: Johnathan Mantey <johnathanx.mantey@xxxxxxxxx> Reviewed-by: Simon Horman <horms@xxxxxxxxxx> Signed-off-by: David S.
