NAME¶
xe —
Xircom PCMCIA Ethernet device
driver
SYNOPSIS¶
To compile this driver into the kernel, place the following line in your kernel
configuration file:
device xe
Alternatively, to load the driver as a module at boot time, place the following
line in
loader.conf(5):
DESCRIPTION¶
The
xe driver supports PCMCIA Ethernet adapters based on
Xircom CE2- and CE3-class hardware. This includes devices made by Xircom along
with various OEM manufacturers.
Please note that the
xe driver only supports PCMCIA cards and
their Ethernet 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 configuring network
interface devices, see
ifconfig(8).

DIAGNOSTICS¶
- xe%d: Cannot allocate ioport
- xe%d: Cannot allocate irq
- A fatal initialization error occurred while attempting to
allocate system resources for the card.
- xe%d: Unable to fix your %s combo
card
- A fatal initialization error occurred while attempting to
attach an Ethernet/modem combo card.
- xe%d: watchdog timeout: resetting
card
- The card failed to generate an interrupt acknowledging a
transmitted packet. May indicate a PCMCIA configuration problem.
- xe%d: no carrier
- The card has lost all contact with the network; this
usually indicates a cable problem.

BUGS¶
Supported devices will fail to attach on some machines using the NEWCARD PC Card
framework.
Automatic media selection is usually unreliable.
