NAME

xe - Xircom PCMCIA Ethernet device driver

SYNOPSIS

To compile this driver into the 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 loader.conf(5):
      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 various OEM manufacturers.

Please note that the xe driver only supports PCMCIA cards

and their Ethernet functions. xe does not support the on-board modem de

vice located
on some version of the Ethernet/modem combo cards. In par

ticular, Xircom
RealPort2 cards are not supported by this driver.

The xe driver supports the following media types:

autoselect Enable autoselection of media type and op

tions.

10Base2/BNC Select 10Mbps operation on a BNC coaxial

connector.

10BaseT/UTP Select 10Mbps operation on a RJ-45 connec

tor.

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 configuring network interface devices, see ifconfig(8).

HARDWARE

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 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.

DIAGNOSTICS

xe%d: Cannot allocate ioport xe%d: Cannot allocate irq A fatal initialization error oc

curred while
attempting to allocate system resources for the card.

xe%d: Unable to fix your %s combo card A fatal initializa

tion 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 configuration problem.

xe%d: no carrier The card has lost all contact with the

network; this
usually indicates a cable problem.

BUGS

Supported devices will fail to attach on some machines using

the NEWCARD
PC Card framework.

Automatic media selection is usually unreliable.
