NAME
     lge — Level 1 LXT1001 NetCellerator PCI Gigabit Ethernet adapter driver

SYNOPSIS
     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device miibus
	   device lge

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

	   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 mar‐
     ket 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) utility con‐
     figures 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).

     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).

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 net‐
     work, or there is a problem with the network connection (cable).
