* - Initial implementation
*
* This is a collection of functions used to control the device (plus
* a few helpers).
*
* There are utilities for handling TLV buffers, hooks on the device's
* reports to act on device changes of state [i2400m_report_hook()],
* on acks to commands [i2400m_msg_ack_hook()], a helper for sending
* commands to the device and blocking until a reply arrives
* [i2400m_msg_to_dev()], a few high level commands for manipulating
* the device state, powersving mode and configuration plus the
* routines to setup the device once communication is stablished with
* it [i2400m_dev_initialize()].
*
* ROADMAP
*
* i2400m_dev_initalize() Called by i2400m_dev_start()
* i2400m_set_init_config()
* i2400m_cmd_get_state()
* i2400m_dev_shutdown() Called by i2400m_dev_stop()
* i2400m_reset()
*
* i2400m_{cmd,get,set}_*()
* i2400m_msg_to_dev()
* i2400m_msg_check_status()
*
* i2400m_report_hook() Called on reception of an event
* i2400m_report_state_hook()
* i2400m_tlv_buffer_walk()
* i2400m_tlv_match()
* i2400m_report_tlv_system_state()
* i2400m_report_tlv_rf_switches_status()
* i2400m_report_tlv_media_status()
* i2400m_cmd_enter_powersave()
*
* i2400m_msg_ack_hook() Called on reception of a reply to a
