2061 The card status event handler. Mostly, this schedules other
2062 stuff to run after an event is received. A CARD_REMOVAL event
2063 also sets some flags to discourage the net drivers from trying
2064 to talk to the card any more.

2066 When a CARD_REMOVAL event is received, we immediately set a flag
2067 to block future accesses to this device. All the functions that
2068 actually access the device should check this flag to make sure
2069 the card is still present.
