IONetworkParameter
An IONetworkParameter manages a named buffer
that is accessible from user space. Each parameter contains a property
that indicates the types of access supported.
By default, only Read access is allowed.
This would allow an user-space application to read the data buffer,
either though the user-client interface, or through the IOKit registry
by serializing the object. An IONetworkParameter instance may also
enable write and reset accesses.
A target/action can be registered in order to receive
notification each time the parameter is accessed.
The main purpose of this object is to export statistics or other
runtime parameters to user-space. The target/action mechanism allows
the target to trap all accesses and update the data buffer only
when needed.
