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.
