Virgin import of Xircom PCCARD driver v1.19.
v1.19 (1999/04/15) updates the CEM56/REM56 support.
Current bugs & misfeatures
--------------------------
* CE2 cards still not working reliably. Unclear if this is related to
packet I/O code or interrupt handling.
* Autonegotiation support remains flaky. We're now OK with 10Mbit auto
hubs, but certain combination of hardware will fail to connect.
