5.4-stable review patch. If anyone has any objections, please let me know.
I have discovered an undesirable side effect caused by this change. If it isn't too late, I'd like to see this change set dropped.
And what is that side effect?
This is already in the following released kernels: 5.4.258 5.10.198 5.15.134 6.1.56 6.5.6 6.6 so please, fix this in Linus's tree and tag the fix for the stable backports as well and all will be good.
The problem discovered: The network link between the BMC NIC reports NO-CARRIER when the carrier is lost from one of the secondary network ports. Restoring carrier on the secondary network port does not restore CARRIER state on the BMC shared interface. Carrier loss and gain on the BMC NIC should only be due to removal/insertion of a network connection to the RJ45 shared by the BMC and host OS.
thanks,
