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.

* 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
