* The NCSI device states seen from external. More NCSI device states are
* only visible internally (in net/ncsi/internal.h). When the NCSI device
* is registered, it's in ncsi_dev_state_registered state. The state
* ncsi_dev_state_start is used to drive to choose active package and
* channel. After that, its state is changed to ncsi_dev_state_functional.
*
* The state ncsi_dev_state_stop helps to shut down the currently active
* package and channel while ncsi_dev_state_config helps to reconfigure
* them.
