NAME

     xi -- Xircom CreditCard Ethernet device driver


SYNOPSIS

     xi* at xirc?

     Configuration of PHYs may also be necessary.  See mii(4).


DESCRIPTION

     The xi driver provides support for the Xircom CreditCard family of PCMCIA
     Ethernet adapters.  Supported cards include:

           Xircom CreditCard Ethernet II
           Xircom CreditCard 10/100 Ethernet
           Xircom RealPort 10/100 Ethernet + Modem (Ethernet function only)
           Intel EtherExpress Pro/100
           Compaq Netelligent 10/100

     Cards which should work, but have not been confirmed include:

           Xircom RealPort Ethernet
           Xircom RealPort 10/100 Ethernet

     Some Xircom Ethernet products are supported by the tlp(4) driver.


MEDIA SELECTION

     Media selection is done using ifconfig(8) using the standard ifmedia(4)
     mechanism.  Refer to those manual pages for more information.


SEE ALSO

     ifmedia(4), mii(4), netintro(4), pcmcia(4), tlp(4), xirc(4), ifconfig(8)


HISTORY

     The xi device driver appeared in NetBSD 1.5.


BUGS

     The driver suffers from poor performance.  Even with the 10/100 cards, do
     not expect more than ~450KB/s.  Some 10/100 cards may not autonegotiate
     reliably and require manual media selection.

     The Xircom multifunction cards which contain both Ethernet and modem
     interfaces are known to have problems.  This is due to the card not
     reporting itself correctly as a multifunction card.
