# lge(4)

Level 1 LXT1001 NetCellerator PCI Gigabit Ethernet adapter driver

## NAME

**lge** – Level 1 LXT1001 NetCellerator PCI Gigabit Ethernet adapter driver

## SYNOPSIS

To compile support for the

**lge** driver into your kernel, place the following lines in your kernel configuration file:

**device miibus** **device lge**

Alternatively, to load the

**lge** driver at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
if_lge_load="YES"
```

## DESCRIPTION

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

The LXT1001 supports fiber PHYs and also a GMII port for use with 10/100/1000 copper PHYs, however there are currently no NICs on the market that use this feature.

The LXT1001 supports TCP/IP checksum offload for receive and VLAN-based filtering as well as a 64-bit multicast hash filter. It also supports jumbo frames, which can be configured via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the [ifconfig(8)](/ifconfig/8.md) utility configures the adapter to receive and transmit jumbo frames. Using jumbo frames can greatly improve performance for certain tasks, such as file transfers and data streaming.

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 [rc.conf(5)](/rc.conf/5.md).

- **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).

## HARDWARE

Adapters supported by the **lge** driver include:

- SMC TigerCard 1000 (SMC9462SX)

- D-Link DGE-500SX

## DIAGNOSTICS

- lge%d: couldn't map memory

  A fatal initialization error has occurred.

- lge%d: couldn't map ports

  A fatal initialization error has occurred.

- lge%d: couldn't map interrupt

  A fatal initialization error has occurred.

- lge%d: no memory for softc struct!

  The driver failed to allocate memory for per-device instance information during initialization.

- lge%d: failed to enable memory mapping!

  The driver failed to initialize PCI shared memory mapping. This might happen if the card is not in a bus-master slot.

- lge%d: no memory for jumbo buffers!

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

- lge%d: watchdog timeout

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