ncsi: Propagate carrier gain/loss events to the NCSI controller

Browse source 
[ Upstream commit 3780bb2931 ]

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.
