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"

DEPRECATION NOTICE

       The      xe     driver     is     not     present     in     FreeBSD     13.0     and     later.      See
       https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more information.

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 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 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.
