42 * The plugin is broken in two main parts: the glue to connman
43 * (iwmx_cm_*() functions) and the glue to the libiWmxSdk (iwmx_sdk_*()
44 * functions). They connect using a well defined interface.
46 * The plugin is state based and operates reactively to state
47 * transtitions on the WiMAX device or to user requests, even from
48 * external control tools that are not aware of connman.
50 * When the user requests connman to do something, it goes into a call
51 * implemented by the 'struct connman_driver iwmx_cm_driver' (or
52 * iwmx_cm_network_driver) that will instruct libiWmxSDK to change the
55 * When the device changes state, a state change callback is sent back
56 * by libiWmxSDK, which gets fed to iwmx_cm_state_change(), which
57 * evaluates the state change and updates connman's internal state in
60 * This allows the device to be also controlled by external tools
61 * without driving connman out of state.
63 * Device's state changes can be caused through:
65 * - connman (by user request)
67 * - any other external utility (eg: WmxSDK's wimaxcu)
69 * - external stimuli: network connection broken when going out of
72 * Functions named __*() normally indicate that require locking. See
77 * When we receive a normal probe request [iwmx_cm_probe()] from
78 * connman, we ignore it (we can tell based on the connman device
81 * The plugin has registered with the WiMAX Network Service and it
82 * will listen to its device add/rm messages [iwmx_sdk_addremove_cb()]
83 * and use that to create a device [iwmx_sdk_dev_add()] which will be
84 * registered with connman. [iwmx_cm_dev_add()]. Then connman will
85 * enumerate the device, call again iwmx_cm_probe() and at this time,
86 * we'll recognize it, pass through iwmx_sdk_setup() and complete the
