|
|
.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.
