sge – Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet driver



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):



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).
  Set 10Mbps operation.
100baseTX Set 100Mbps (Fast Ethernet) operation.
1000baseTX Set 1000baseTX operation over twisted pair.

The sge driver supports the following media options:
  Force full duplex operation.
  Force half duplex operation.

For more information on configuring this device, see ifconfig(8).


The sge device driver provides support for the following Ethernet controllers:


altq(4), arp(4), miibus(4), netintro(4), ng_ether(4), rgephy(4), vlan(4), ifconfig(8)


The sge driver was written by Alexander Pohoyda <Mt alexander.pohoyda@gmx.net>. And enhanced by Nikolay Denev <Mt ndenev@gmail.com>. It first appeared in FreeBSD 8.1 .
