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):
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).
