xe -- Xircom PCMCIA Ethernet device driver
The xe driver supports PCMCIA Ethernet adapters based on Xircom CE2- and
CE3-class hardware. This includes devices made by Xircom along with var-
ious OEM manufacturers.
Please note that the xe driver only supports PCMCIA cards and their Eth-
ernet functions. xe does not support the on-board modem device located
on some version of the Ethernet/modem combo cards. In particular, Xircom
RealPort2 cards are not supported by this driver.
The xe driver supports the following media types:
autoselect Enable autoselection of media type and options.
Select 10Mbps operation on a BNC coaxial connector.
Select 10Mbps operation on a RJ-45 connector.
100BaseTX Select 100Mbps operation.
Note that 100BaseTX operation is not available on CE2-class cards, while
the 10Base2/BNC mode is only available on CE2-class cards. Full-duplex
operation is currently not supported. For more information on configur-
ing network interface devices, see ifconfig(8).
The xe driver supports the following cards:
o Xircom CreditCard Ethernet (PS-CE2-10)
o Xircom CreditCard Ethernet + Modem 28 (PS-CEM-28)
o Xircom CreditCard Ethernet + Modem 33 (CEM33)
o Xircom CreditCard 10/100 (CE3, CE3B)
o Xircom CreditCard Ethernet 10/100 + Modem 56 (CEM56)
o Xircom RealPort Ethernet 10 (RE10)
o Xircom RealPort Ethernet 10/100 (RE100)
o Xircom RealPort Ethernet 10/100 + Modem 56 (REM56, REM56G)
o Accton Fast EtherCard-16 (EN2226)
o Compaq Netelligent 10/100 PC Card (CPQ-10/100)
o Intel EtherExpress Pro/100 PC Card Mobile Adapter 16 (Pro/100 M16A)
o Intel EtherExpress Pro/100 LAN/Modem PC Card Adapter (Pro/100 M16B)
Other similar devices using the same hardware may also be supported.
xe%d: Cannot allocate ioport
xe%d: Cannot allocate irq A fatal initialization error occurred while
attempting to allocate system resources for the card.
xe%d: Unable to fix your %s combo card A fatal initialization error
occurred while attempting to attach an Ethernet/modem combo card.
xe%d: watchdog timeout: resetting card The card failed to generate an
interrupt acknowledging a transmitted packet. May indicate a PCMCIA con-
xe%d: no carrier The card has lost all contact with the network; this
usually indicates a cable problem.
The xe driver first appeared in FreeBSD 3.3.
The xe device driver was written by Scott Mitchell <rsmATFreeBSD.org>.

Supported devices will fail to attach on some machines using the NEWCARD
PC Card framework.
Automatic media selection is usually unreliable.
