Hi Everyone,

The attached files represent a proposed dbus based API to access the
Linux WiMax stack.  This proposal is the result of a number of
discussions over the last few months at OLS and the plumbers
conference. 

Overview:
There are two object types used to access the WiMax stack the adapter
and network object.  

The adapter (adapter-api.txt) object is created when the hardware
device is discovered in the system. This object is used to control the
state of the adapter and the process of scanning for available
networks.

The network (network-api.txt) object is created when a network is
discovered via the adapter.Scan() method.  This object is used to
control the state and report information about available network
connections. 

There is one helper agent (agent-api.txt) that is meant to call out to
gather user credentials i.e.(username, password).  The current file is
just a placeholder.

Comments and suggestions gratefully accepted.

TIA

                        This unregisters the agent that has been previously
                        registered. The object path parameter must match the

                NetworkFound(string address, dict values)

                        This signal will be send every time an scan result
                        has been found by the adapter. 

                        The dictionary can contain bascially the same values
                        that we be returned by the GetProperties method

The agent API provides an interface for the wimax adapter object to
obtain credential/login information from the user.

NOTE This file is a placeholder and will be fleshed out with the
methods required as the usage model of the adapter and network objects
are finalized.

Agent hierarchy
===============

Service         org.wimax
Interface       org.wimax.Agent
Object path     freely definable

Methods         void Release()

                        This method gets called when the service daemon
                        unregisters the agent. An agent can use it to do
                        cleanup tasks. There is no need to unregister the
                        agent, because when this method gets called it has
                        already been unregistered.


                void Cancel()

                        This method gets called to indicate that the agent
                        request failed before a reply was returned.

This file will be used to track open issues for the Linux WiMax DBUS
API.  Once an issue is resolved the issue will be moved to the
"Closed" seciton.

Open Issues:

#1. Should the Scan and ScanWide adapter method calls be collapsed
    into a single method accepting a single boolean argument
    controlling the type of scan proceedure performed.

#2. Should the idea of configured "profiles" be part of the standard
    D-Bus API or left to be vendor specific.

#3. Should NspContactInfoText and NspContactInfoURI properties in the
    network object remain strings or be some type of structured
    information.
   
#4. Should all state transitions for the adapter and network objects
    be signalled from a single object or be split across network and
    adapter implementations. 

#5. The complete set of error signals needs definition.

#6. The credential agent API needs to be defined the current
    agent-api.txt is just a place holder.  

#7.
