.Sh NAME
.Nm xi
.Nd Xircom CreditCard Ethernet device driver
.Sh SYNOPSIS
.Cd "xi* at pcmcia? function ?
.Pp
Configuration of PHYs may also be necessary. See
.Xr mii 4 .
.Sh DESCRIPTION
The
.Nm
driver provides support for the Xircom CreditCard family of PCMCIA
Ethernet adapters. Supported cards include:
.Pp
.Bl -item -compact -offset indent
.It
Xircom CreditCard Ethernet II
.It
Xircom CreditCard 10/100 Ethernet
.\" .It Xircom CreditCard Ethernet + Modem
.\" .It Xircom CreditCard 10/100 Ethernet + Modem
.It
Xircom RealPort 10/100 Ethernet + Modem (Ethernet function only)
.It
Intel EtherExpress Pro/100
.It
Compaq Netelligent 10/100
.El
.Pp
Cards which should work, but have not been confirmed include:
.Pp
.Bl -item -compact -offset indent
.It
Xircom RealPort Ethernet
.It
Xircom RealPort 10/100 Ethernet
.El
.Pp
Some Xircom Ethernet products are supported by the
.Xr tlp 4
driver.
.Sh MEDIA SELECTION
Media selection is done using
.Xr ifconfig 8
using the standard
.Xr ifmedia 4
mechanism. Refer to those manual pages for more information.
.Sh SEE ALSO
.Xr ifmedia 4 ,
.Xr mii 4 ,
.Xr netintro 4 ,
.Xr pcmcia 4 ,
.Xr tlp 4 ,
.Xr ifconfig 8
.Sh HISTORY
The
.Nm
device driver appeared in
.Nx 1.5 .
.Sh 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.
.Pp
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.
