Level 1 LXT1001 NetCellerator PCI 1Gb Ethernet device

## NAME

**lge** – Level 1 LXT1001 NetCellerator PCI 1Gb Ethernet device

## SYNOPSIS

**lge\* at pci?** **xmphy\* at mii?**

## DESCRIPTION

The **lge** driver provides support for various NICs based on the Level 1 LXT1001 NetCellerator Gigabit Ethernet controller chip, including the following:

- Allied Telesis CentreCOM LA1000-PCI-SX

- D-Link DGE-500SX

- SMC TigerCard 1000 (SMC9462SX)

These NICs are capable of 1000Mbps speeds over fiber optic cable. The LXT1001 also supports a GMII port for use with 10/100/1000 copper PHYs, however there aren't currently any NICs on the market that use this feature.

The LXT1001 supports IPv4 receive IP/TCP/UDP checksum offload as well as a 64-bit multicast hash filter. It also supports jumbo frames.

The **lge** driver supports the following media types:

- **autoselect**

  Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the appropriate [hostname.if(5)](/hostname.if/5.md) file.

- **1000baseSX**

  Set 1000baseSX operation over fiber optic cable. Both **full-duplex** and **half-duplex** modes are supported.

The **lge** driver supports the following media options:

- **full-duplex**

  Force full duplex operation.

- **half-duplex**

  Force half duplex operation.

For more information on configuring this device, see [ifconfig(8)](/ifconfig/8.md).

## DIAGNOSTICS

- lge0: can't map i/o space

  A fatal initialization error has occurred.

- lge0: couldn't map interrupt

  A fatal initialization error has occurred.

- lge0: no memory for jumbo buffer queue!

  The driver failed to allocate memory for jumbo frames during initialization.

- lge0: watchdog timeout

  The device has stopped responding to the network, or there is a problem with the network connection (cable).
