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 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 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).
