# 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

# 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.
