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="YES"

DESCRIPTION
     The sge device driver provides support for SiS190 Fast Ethernet con‐
     trollers 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 sup‐
     ported 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).
