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.

APLICATION PROGRAMING INTERFACE
     The afe driver can be used as either a "style 1" or a "style
     2" Data Link Service Provider. Physical points of attachment
     (PAs) are interpreted as the instance  number  of  the  afe
     controller as assigned by the Solaris operating environment.


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

         o    Maximum SDU is 1500.

         o    Minimum SDU is 0.

         o    The dlsap address length is 8.

         o    MAC type is DLETHER.

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

         o    Service mode is DLCLDLS.

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


     If the SAP provided is zero, then IE 802.3 mode is assumed
     and outbound frames will have the frame payload length writ-
     ten into the type field. Likewise, inbound frames with a SAP
     between  zero  and 1500 are interpreted as IE 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):

     advautonegcap

         Enables  (default)  or  disables   IE   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 IE 802.3u  speci-
         fied preferences.


     adv100T4cap

         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.)


     adv100fdxcap

         Enables the 100 Base TX full-duplex link  option.  (This
         is generally the fastest mode if both link partners sup-
         port it. Most modern equipment supports this mode.)


     adv100hdxcap

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


     adv10fdxcap

         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.)


     adv10hdxcap

         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.)
