     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



     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.
