The card status event handler. Mostly, this schedules other

2122 |

|
stuff to run after an event is received. A CARD_REMOVAL event
|
2123 |
|
|
also sets some flags to discourage the net drivers from trying

2124 |
|
|
to talk to the card any more.
|
2125 |

|
|
2126 |
|
|
When a CARD_REMOVAL event is received, we immediately set a flag
|
2127 |
|
|
to block future accesses to this device. All the functions that
|
2128 |
|
|
actually access the device should check this flag to make sure
|
2129 |

the card is still present.
