LGE(4) OpenBSD Programmer's Manual LGE(4)NAMElge - Level 1 LXT1001 NetCellerator PCI Gigabit Ethernet device
SYNOPSIS
lge* at pci?
xmphy* at mii?
DESCRIPTION
The lge driver provides support for various NICs based on the Level 1
LXT1001 NetCellerator Gigabit Ethernet controller chip, including the
following:
o Allied Telesis CentreCOM LA1000-PCI-SX
o D-Link DGE-500SX
o SMC TigerCard 1000 (SMC9462SX)
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 IPv4 receive IP/TCP/UDP checksum offload 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
lge%d: can't map i/o space A fatal initialization error has occurred.
lge%d: couldn't map interrupt A fatal initialization error has occurred.
lge%d: no memory for jumbo buffer queue! 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).
