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