OID_WWAN_PRESHUTDOWN
OID_WWAN_PRESHUTDOWN is sent to notify the modem that the system is entering the shutdown phase and the modem should finish its operations so it can be shut down properly. It is only sent down with the port number corresponding to the physical MBB adapters. Virtual adapters that support multiple PDP contexts should not receive this OID.
Query requests are not supported.
Miniport drivers must process set requests asynchronously, initially returning NDIS_STATUS_INDICATION_REQUIRED to the original request, and later sending a NDIS_STATUS_WWAN_PRESHUTDOWN_STATE status notification when the MBB driver has finished all necessary modem operations prior to shutting down. The set request has a NDIS_WWAN_SET_PRESHUTDOWN_STATE structure.
Miniport drivers should return NDIS_STATUS_NOT_SUPPORTED if they do not support this operation.
