Status Indications in an Intermediate Driver
The implementation of status indications in intermediate drivers is nearly identical to the implementation in protocol drivers. For more information about intermediate driver status indications, see Status Indications in a Protocol Driver.
When an intermediate driver receives a status indication, it can indicate the status indication up to the higher-level drivers by calling NdisMIndicateStatusEx. An intermediate driver should indicate status changes to overlying drivers as appropriate for its specific design requirements.
