.Sh DESCRIPTION
|
|
The
|
|
.Nm

|
interface provides a consistent method for querying and setting
|
|
network inerface media and media options. The media is typically
|
|
set using the
|
|
.Xr ifconfig 8
|
|
command.
|
|
.Pp

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
interface first appeared in
|
|
.Bsx 3.0 .
|
|
The implementation that appeared in
|
|
.Nx 1.3
|
|
was written by Jonathan Stone and Jason R. Thorpe to be compatible with
|
|
the BSDI API. It has since gone through several revisions which have
|
|
extended the API while maintaining backwards compatibility with the
|
|
original API.
