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