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 ob-
     ject, exactly one of the following options may be placed in thge kernel
     configuration file:

     MIDWAY_ADPONLY  Include support for Adaptec interfaces only.

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


BUGS

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