5.4-stable review patch. If anyone has any objections, please let me know.

From: Johnathan Mantey johnathanx.mantey@intel.com
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
