As fm10k host interface is not directly connected to PHY, marking the link
status as UP doesn't mean a lot to the application. So, this patch
basically redefines the link status as the state of switch manager: when
switch manager is running, it's LINK_UP; when switch manager goes down by
calling the fmTerminate function, status turns to LINK_DOWN.
