NAME
xe -- Xircom PCMCIA Ethernet device driver
SYNOPSIS
To compile this driver into your kernel, place the following line in your
kernel configuration file:
device xe
Alternatively, to load the driver as a module at boot time, place the
following line in /boot/loader.conf:
if_xe_load="YES"
DESCRIPTION
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.
10Base2/BNC
Select 10Mbps operation on a BNC coaxial connector.
10BaseT/UTP
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).
HARDWARE
The xe driver supports the following cards:
* Xircom CreditCard Ethernet (PS-CE2-10)
* Xircom CreditCard Ethernet + Modem 28 (PS-CEM-28)
* Xircom CreditCard Ethernet + Modem 33 (CEM33)
* Xircom CreditCard 10/100 (CE3, CE3B)
* Xircom CreditCard Ethernet 10/100 + Modem 56 (CEM56)
* Xircom RealPort Ethernet 10 (RE10)
* Xircom RealPort Ethernet 10/100 (RE100)
* Xircom RealPort Ethernet 10/100 + Modem 56 (REM56, REM56G)
* Accton Fast EtherCard-16 (EN2226)
* Compaq Microcom CPQ550 Ethernet/Modem PC Card
* Compaq Netelligent 10/100 PC Card (CPQ-10/100)
* Intel EtherExpress Pro/100 PC Card Mobile Adapter 16 (Pro/100 M16A)
* Intel EtherExpress Pro/100 LAN/Modem PC Card Adapter (Pro/100 M16B)
Other similar devices using the same hardware may also be supported.
DIAGNOSTICS
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-
figuration problem.
xe%d: no carrier The card has lost all contact with the network; this
usually indicates a cable problem.
