NAME
     mxfe - MXFE Fast Ethernet device driver

SYNOPSIS
     /dev/mxfe*


DESCRIPTION
     The mxfe is a Solaris STREAMS hardware driver supporting the
     Data  Link  Provider  Interface (dlpi(7P)) over the Macronix
     98715 family (including the Lite-On PNIC-I) of Fast  Ether-
     net controllers.

DLPI SPECIFICATIONS
     The mxfe driver supports both style 1 and style 2  modes  of
     operation.  Physical  points of attachment (PAs) are inter-
     preted as the instance number of  the   mxfe  controller  as
     assigned by the operating system.


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

         o    Maximum SDU is 1500.

         o    Minimum SDU is 0.

         o    DLSAP address length is 8.

         o    MAC type is DLETHER.

         o    SAP  length  value  is  -2,  meaning  the  physical
              address  component  is followed immediately by a 2-
              byte SAP component within the DLSAP address.

         o    Service mode is DLCLDLS.

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


     If the SAP provided is zero, IE 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 IE 802.3 frames
     and delivered to streams that have bound to  SAP  zero  (the
     802.3 SAP).
