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. Developed by: Scott Mitchell <scott@uk.freebsd.org> Obtained from: http://www.freebsd-uk.eu.org/~scott/xe_drv/

* 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.
