# 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) 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).
