NAME

     xe -- Xircom PCMCIA Ethernet device driver

SYNOPSIS

     device xe

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).
