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-II) of Fast Ethernet controllers.

DLPI SPECIFICATIONS

       The mxfe driver supports both style 1 and style 2 modes of operation. Physical points of attachment (PPAs) are interpreted as the  instance
       number of the  mxfe controller as assigned by the operating system.

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

	   o	  Maximum SDU is 1500.

	   o	  Minimum SDU is 0.

	   o	  DLSAP address length is 8.

	   o	  MAC type is DL_ETHER.

	   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 DL_CLDLS.

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

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