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-duplexandhalf-duplexmodes 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).
