This document describes the interface for the second generation unix MSNL implementation which uses kernel data paths and user space control.
The interface consists of messages passed over a back door raw socket. The interface is liable to change from the one described herein. The interface is unashamedly optimised for the kernel for implementation reasons.
There are three different types of message which are sent between the kernel and user space code. These deal with the management of sockets, the management of associations and the initialisation of the port code.
