| 8 | * The NCSI device states seen from external. More NCSI device states are
|
| 9 | * only visible internally (in net/ncsi/internal.h). When the NCSI device
|
| 10 | * is registered, it's in ncsi_dev_state_registered state. The state
|
| 11 | * ncsi_dev_state_start is used to drive to choose active package and
|
| 12 | * channel. After that, its state is changed to ncsi_dev_state_functional.
|
| 13 | *
|
| 14 | * The state ncsi_dev_state_stop helps to shut down the currently active
|
| 15 | * package and channel while ncsi_dev_state_config helps to reconfigure
|
| 16 | * them.
