NAME

     ieef - Intel Ethernet device driver

SYNOPSIS

     /kernel/drv/ieef

DESCRIPTION

     The ieef driver currently supports  the  Intel  EtherExpress
     Flash  (ISA) and Intel 82256 EEpro100 Ethernet (PCI) network
     cards.

     The ieef Ethernet  driver  is  a  multi-threaded,  loadable,
     clonable, STREAMS hardware driver supporting the connection-
     less Data Link Provider Interface, dlpi(7P).  Multiple  con-
     trollers  installed  within  the system are supported by the
     driver.  The ieef driver  provides  basic  support  for  the
     hardware.   Functions  include  chip  initialization,  frame
     transmit and receive, multicast and  promiscuous  mode  sup-
     port, and error recovery and reporting.

     The cloning, character-special device /dev/ieef is  used  to
     access all Intel devices installed within the system.

     The ieef driver is dependent on /kernel/misc/gld, a loadable
     kernel  module  that  provides the ieef driver with the DLPI
     and STREAMS functionality required  of  a  LAN  driver.  See
     gld(7D)  for more details on the primatives supported by the
     driver.

     The values returned by the driver in the DL_INFO_ACK  primi-
     tive  in  response  to  the DL_INFO_REQ from the user are as
     follows:

        o  Maximum SDU is 1500 (ETHERMTU).

        o  Minimum SDU is 0. The driver will pad to the mandatory
           60-octet minimum packet size.

        o  The dlsap address length is 8.

        o  MAC type is DL_ETHER.

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

        o  The broadcast address value is Ethernet/IEEE broadcast
           address (FF:FF:FF:FF:FF:FF).

PRECONFIGURATION

  Known Problems and Limitations

     The ieef driver provides 100-Mbps  Ethernet  support.   Note
     that  the  driver  does not currently transfer data at rates
     expected of a 100-Mbps interface.

CONFIGURATION

     The /kernel/drv/ieef.conf file supports the ioaddr and  intr
     options
