NDISsulator: Setting up a 3Com pc card

[Ted Lindgreen]

Two more panic messages:

Sep 21 12:17:05 petje kernel: panic: page fault
....

These two panics are reproducable with a basestation without and
with WEP enabled.

Without WEP, the current process is ndis swi and the panic occurs
short (but not immediately) after ifconfig...up.

With WEP the panic happens immediately when ifconfig has set and
enabled the key in the card, and the current process is ifconfig.

It looks like the panic occurs at the moment when a packet is
received/accepted by the pccard.
