XI(4)

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.

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.
