lgeLevel 1 LXT1001 NetCellerator PCI Gigabit Ethernet device

lge* at pci?
xmphy* at mii?

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

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:

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

The lge driver supports the following media options:

Force full duplex operation.
Force half duplex operation.

For more information on configuring this device, see ifconfig(8).
