FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

lge - Level 1 LXT1001 NetCellerator PCI Gigabit Ethernet adapter driver

 

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).

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
