NAME

     en -- Midway-based ATM interfaces device driver


SYNOPSIS

     en* at pci? dev ? function ?
     en* at sbus? slot ? offset ?


DESCRIPTION

     The en device driver supports Midway-based ATM interfaces including the
     Efficient Networks, Inc. ENI-155 and Adaptec 5900 and 5905.


OPTIONS

     The Efficient Networks, Inc. and Adaptec interfaces use significantly
     different DMA engines.  In order to reduce the size of the en driver
     object, exactly one of the following options may be placed in the kernel
     configuration file:

     MIDWAY_ADPONLY  Include support for Adaptec interfaces only.

     MIDWAY_ENIONLY  Include support for Efficient Networks, Inc. interfaces
                     only.


HARDWARE

     Cards supported by the en driver include:

     Efficient Networks, Inc. ENI-155
     Adaptec 5900 and 5905


SEE ALSO

     intro(4), pci(4), sbus(4), ifconfig(8)


BUGS

     The Sbus attachment of the en driver only currently functions on sun4c
     class systems.
