LGE(4)                   BSD Kernel Interfaces Manual                   LGE(4)

NAME
     lge -- Level 1 LXT1001 NetCellerator PCI Gigabit 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:

     o   Allied Telesis CentreCOM LA1000-PCI-SX
     o   D-Link DGE-500SX
     o   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 fea-
     ture.

     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).

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).
