     lge - Level 1 LXT1001  NetCellerator  PCI  Gigabit  Ethernet
adapter driver

SYNOPSIS    [Toc]    [Back]

     lge* at pci? dev ? function ?

DESCRIPTION    [Toc]    [Back]

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

     +o   SMC TigerCard 1000 (SMC9462SX)
     +o   D-Link DGE-500SX

     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 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 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    [Toc]    [Back]

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