Disconnections are reported to CSME as long link down. As a result,
CSME will take ownership right away so the host doesn't have a
chance to reconnect, although in many cases it could quickly reconnect
and preserve host connectivity.
Report disconnections as temporary so CSME will give the host some
grace time to reconnect.
