NAME
       lge  -- Level 1 LXT1001 NetCellerator PCI Gigabit Ethernet adapter dri-
       ver

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
       market 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
       configures 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  oc-
       curred.

       lge%d:  no memory for softc struct!  The	driver failed to allocate mem-
       ory for per-device instance information during initialization.

       lge%d: failed to	enable memory mapping!	The driver failed to  initial-
       ize 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 mem-
       ory 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).
