NAME

       sfe - SiS900 series Fast Ethernet device driver

SYNOPSIS

       /dev/sfe

DESCRIPTION

       The  sfe  driver  is  a loadable, clonable, GLD-based  STREAMS driver supporting the Data Link Provider Interface dlpi(7P) on Silicon Inte-
       grated Systems 900 series Fast Ethernet controllers.

APPLICATION PROGRAMMING INTERFACE

       The relevant fields returned as part of a DL_INFO_ACK response are:

	   o	  Maximum SDU is 1500.

	   o	  Minimum SDU is 0.

	   o	  The dlsap address length is 8.

	   o	  MAC type is DL_ETHER.

	   o	  SAP length is -2. The 6-byte physical address is followed immediately by a 2-byte SAP.

	   o	  Service mode is DL_CLDLS.

	   o	  Broadcast address is the 6-byte Ethernet broadcast address (ff:ff:ff:ff:ff:ff).

       If the SAP provided is zero, then IEEE 802.3 mode is assumed and outbound frames will have the frame payload length written into  the  type
       field. Likewise, inbound frames with a SAP between zero and 1500 are interpreted as IEEE 802.3 frames and delivered to any streams that are
       bound to SAP zero (the 802.3 SAP).

PROPERTIES

       The following properties  may  be  configured  using  either ndd(1M) or the sfe.conf configuration file as described by driver.conf(4):

       adv_100fdx_cap

	   Enables the 100 Base TX full-duplex link option. (This is generally the fastest mode if both link  partners	support  it.  Most  modern
	   equipment supports this mode.)

       adv_100hdx_cap

	   Enables the 100 Base TX half-duplex link option. (Typically used when the link partner is a 100 Mbps hub.)

       adv_10fdx_cap

	   Enables  the  10  Base-T full-duplex link option.  (This less-frequently used mode is typically used when the link partner is a 10 Mbps
	   switch.)

       adv_10hdx_cap

	   Enables the 10 Base-T half-duplex link option.  (This is the fall-back when no other option is available.  It is  typically	used  when
	   the link partner is a 10 Mbps hub or is an older network card.)
