.SH NAME
efe \- EPIC/100 Fast Ethernet device driver

.SH SYNOPSIS
.LP
.nf
\fB/dev/efe\fR
.fi

.SH DESCRIPTION
.sp
.LP
The \fBefe\fR driver is a multi-threaded, loadable, clonable, GLD-based STREAMS
driver supporting the Data Link Provider Interface \fBdlpi\fR(7P) on SMC
EtherPower II (9432TX) Fast Ethernet controllers.

.SH APPLICATION PROGRAMMING INTERFACE
.sp
.LP
The values returned by the driver in the DL_INFO_ACK primitive in response to a
DL_INFO_REQ are:
.RS +4
.TP
.ie t \(bu
.el o
Maximum SDU is 1500.
.RE
.RS +4
.TP
.ie t \(bu
.el o
Minimum SDU is 0. The driver pads to the mandatory 60-octet minimum
packet size.
.RE
.RS +4
.TP
.ie t \(bu
.el o
DLSAP address length is 8.
.RE
.RS +4
.TP
.ie t \(bu
.el o
MAC type is \fBDL_ETHER\fR.
.RE
.RS +4
.TP
.ie t \(bu
.el o
\fBSAP\fR length value is \fI-2\fR, meaning the physical address component is
followed immediately by a 2-byte \fBSAP\fR component within the \fBDLSAP\fR
address.
.RE
.RS +4
.TP
.ie t \(bu
.el o
Broadcast address value is the Ethernet/IEEE broadcast address
(FF:FF:FF:FF:FF:FF).
.RE
.sp
.LP
Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a
particular Service Access Point (SAP) with the stream.

.SH CONFIGURATION
.sp
.LP
The following capabilities are supported by the \fRefe\fR driver:
.RS +4
.TP
.ie t \(bu
.el o
100 Mbps, full-duplex
.RE
.RS +4
.TP
.ie t \(bu
.el o
100 Mbps, half-duplex
.RE
.RS +4
.TP
.ie t \(bu
.el o
10 Mbps, full-duplex
.RE
.RS +4
.TP
.ie t \(bu
.el o
10 Mbps, half-duplex
.RE
.sp
.LP
Individual link properties may be configured using the \fBdladm\fR(1M)
command line utility.
