To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device miibusdevice lge
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
if_lge_load="YES"
DESCRIPTION
The
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
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.conf5.
1000baseSX
Set 1000baseSX operation over fiber optic cable.
Both
full-duplex
and
half-duplex
modes are supported.
The
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
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).
