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  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
       configuring network interface devices, see ifconfig(8).

HARDWARE

       The xe driver supports the following cards:

       •   Xircom CreditCard Ethernet (PS-CE2-10)

       •   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 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.
