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


To compile this driver into the kernel, place the following lines in your kernel configura‐ tion 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"


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).


The sge device driver provides support for the following Ethernet controllers: · SiS190 Fast Ethernet controller · SiS191 Fast/Gigabit Ethernet controller


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 <>. And enhanced by Nikolay Denev <>. It first appeared in FreeBSD 8.1.
