NAME
       afe - ADMtek Fast Ethernet device driver

SYNOPSIS
       /dev/afe

DESCRIPTION
       The afe driver is a multi-threaded,  loadable, clonable, GLD-based  STREAMS  driver supporting the Data Link Provider Interface dlpi(7P) on
       ADMtek (now Infineon) Centaur and Comet Fast Ethernet controllers.

APPLICATION PROGRAMMING INTERFACE
       The afe driver can be used as either a "style 1" or a "style 2" Data Link Service Provider. Physical points of attachment (PPAs) are inter-
       preted as the instance  number of the afe controller as assigned by the Solaris operating environment.

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

	   o	  Maximum SDU is 1500.

	   o	  Minimum SDU is 0.

	   o	  The dlsap address length is 8.

	   o	  MAC type is DL_ETHER.

	   o	  SAP length is -2. The 6-byte physical address is followed immediately by a 2-byte SAP.

	   o	  Service mode is DL_CLDLS.

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

       If  the	SAP provided is zero, then 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 any streams that are
       bound to SAP zero (the 802.3 SAP).

PROPERTIES
       The following properties  may  be  configured  using  either ndd(1M) or the afe.conf configuration file as described by driver.conf(4):

       adv_autoneg_cap

	   Enables  (default)  or disables IEEE 802.3u auto-negotiation of link speed and duplex settings. If enabled, the device negotiates among
	   the supported (and configured, see below) link options with the link partner.  If disabled, at least one of the link options below must
	   be specified. The driver selects the first enabled link option according to the IEEE 802.3u specified preferences.

       adv_100T4_cap

	   Enables  the  100 BaseT4 link option.  (Note that most hardware does not support this unusual link style.  Also, this uses two pairs of
	   wires for data, rather than one.)

       adv_100fdx_cap

	   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.)

       adv_100hdx_cap

	   Enables the 100 Base TX half-duplex link option. (Typically used when the link partner is a 100 Mbps hub.)

       adv_10fdx_cap

	   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.)

       adv_10hdx_cap

	   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.)
