.SH NAME
sfe \- SiS900 series Fast Ethernet device driver
.SH SYNOPSIS

.SH DESCRIPTION
.sp
.LP
The \fBsfe\fR driver is a loadable, clonable, GLD-based  STREAMS driver
supporting the Data Link Provider Interface \fBdlpi\fR(7P) on Silicon
Integrated Systems 900 series Fast Ethernet controllers.

If the SAP provided is zero, then \fIIEEE 802.3\fR 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
\fIIEEE 802.3\fR frames and delivered to any streams that are bound to SAP zero
(the \fI802.3\fR SAP).
.SH PROPERTIES

The following properties  may  be  configured  using  either \fBndd\fR(1M) or
the \fBsfe.conf\fR configuration file as described by \fBdriver.conf\fR(4):
.sp
.ne 2
.na
\fB\fBadv_100fdx_cap\fR\fR
.ad
.sp .6
.RS 4n
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.)
.RE

.sp
.ne 2
.na
\fB\fBadv_100hdx_cap\fR\fR
.ad
.sp .6
.RS 4n
Enables the 100 Base TX half-duplex link option. (Typically used when the link
partner is a 100 Mbps hub.)
.RE

.sp
.ne 2
.na
\fB\fBadv_10fdx_cap\fR\fR
.ad
.sp .6
.RS 4n
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.)
.RE

.sp
.ne 2
.na
\fB\fBadv_10hdx_cap\fR\fR
.ad
.sp .6
.RS 4n
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.)
