Virgin import of Xircom PCCARD driver v1.19.

Browse Source 
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.

/*
* FreeBSD device driver for Xircom CreditCard PCMCIA Ethernet adapters. The
* following cards and media are, or will eventually be, supported (Ethernet
* part only on the multifunction CEM cards):
* CE2 10BASE-2, 10BASE-T (I think)
* CEM28 ditto
* CEM33 ditto
* CE3 10BASE-T, 100BASE-TX
* CEM56 ditto
* RealPort ditto
* Compaq and Intel cards using the Xircom CE3 hardware are also known to
* work. See the website for full details of supported hardware.
* following cards are currently known to work with the driver:
* Xircom CreditCard 10/100 (CE3)
* Xircom CreditCard Ethernet 10/100 + Modem 56 (CEM56)
* Xircom RealPort Ethernet 10/100
* Xircom RealPort Ethernet 10/100 + Modem 56 (REM56, REM56G)
* Intel EtherExpress Pro/100 PC Card Mobile Adapter 16 (Pro/100 M16A)
* Compaq Netelligent 10/100 PC Card (CPQ-10/100)
*
* Some other cards *should* work, but support for them is either broken or in
* an unknown state at the moment. I'm always interested in hearing from
* people who own any of these cards:
* Xircom CreditCard 10Base-T (PS-CE2-10)
* Xircom CreditCard Ethernet + ModemII (CEM2)
* Xircom CEM28 and CEM33 Ethernet/Modem cards (may be variants of CEM2?)
*
* Thanks to all who assisted with the development and testing of the driver,
* especially: Werner Koch, Duke Kamstra, Duncan Barclay, Ade Lovett, Jason
* George, Dru Nelson, Mike Kephart, Bill Rainey and Douglas Rand. Apologies
* if I've left out anyone who deserves a mention here.
