On the DM9000A/DM9000B force the initial check of the link status.  The
DM9000A/B has a link status changed event and this interrupt bit isn't
always set out of reset when a cable is plugged in.  This results in the
driver not seeing the cable attached link status until the cable is
removed and plugged in again.
