ncsi: Propagate carrier gain/loss events to the NCSI controller
[ Upstream commit 3780bb29311eccb7a1c9641032a112eed237f7e3 ]
Report the carrier/no-carrier state for the network interface
shared between the BMC and the passthrough channel. Without this
functionality the BMC is unable to reconfigure the NIC in the event
of a re-cabling to a different subnet.
