.Nd Midway-based ATM interfaces device driver
.Sh SYNOPSIS
.Cd "en* at pci? dev ? function ?"
.Cd "en* at sbus? slot ? offset ?"
.Sh DESCRIPTION
The
.Nm
device driver supports Midway-based
.Tn ATM
interfaces including the
Efficient Networks, Inc. ENI-155 and Adaptec 5900 and 5905.
.Sh OPTIONS
The Efficient Networks, Inc. and Adaptec interfaces use significantly
different DMA engines.
In order to reduce the size of the
.Nm
driver object, exactly one of the following options may be placed
in the kernel configuration file:
.Bl -tag -width MIDWAY_ADPONLY
.It MIDWAY_ADPONLY
Include support for Adaptec interfaces only.
.It MIDWAY_ENIONLY
Include support for Efficient Networks, Inc. interfaces only.
