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(4P) on Silicon
Integrated 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(8) or
the sfe.conf configuration file as described by driver.conf(5):

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.)
