SGE(4)

NAME
sge - Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet driver

SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:

device miibus
device sge

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

    if_sge_load="YES"

DESCRIPTION
The sge device driver provides support for SiS190 Fast Ethernet controllers and SiS191 Fast/Gigabit Ethernet controllers.

All LOMs supported by the sge driver have TCP/UDP/IP checksum offload for transmit and receive, TCP segmentation offload (TSO), hardware VLAN tag stripping/insertion features. Due to lack of documentation Wake On Lan (WOL), Jumbo frame and an interrupt moderation mechanism are not supported yet.

The sge 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).

10baseT/UTP
    Set 10Mbps operation.

100baseTX
    Set 100Mbps (Fast Ethernet) operation.

1000baseTX
    Set 1000baseTX operation over twisted pair.

The sge 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).
