mxfe \- MXFE Fast Ethernet device driver
.SH SYNOPSIS

.SH DESCRIPTION
.sp
.LP
The \fBmxfe\fR is a Solaris STREAMS hardware driver supporting the Data Link
Provider Interface (\fBdlpi\fR(7P)) over the Macronix 98715 family (including
the Lite-On PNIC-II) of Fast Ethernet controllers.
.SH DLPI SPECIFICATIONS
.sp
.LP
The \fBmxfe\fR driver supports both style 1 and style 2 modes of operation.
Physical points of attachment (PPAs) are interpreted as the instance number of
the  \fBmxfe\fR controller as assigned by the operating system.

\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.

If the SAP provided is zero, \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 streams that have bound to SAP zero (the
\fI802.3\fR SAP).
