Handling PnP Event Notifications in a Protocol Driver

  • Artikel

NDIS 6.0 and later protocol drivers handle the same Plug and Play (PnP) event notifications as NDIS 5.x drivers in addition to event notifications that are specific to NDIS 6.0 and later. The handling of PnP event notifications is driver specific.

To notify a protocol driver of a network PnP event, NDIS calls the driver's ProtocolNetPnPEvent function. To define the type of event and characteristics of the event, NDIS passes a NET_PNP_EVENT_NOTIFICATION structure at the NetPnPEvent event parameter of ProtocolNetPnPEvent.

Protocol drivers should handle driver stack changes. For more information about driver stack changes, see Modifying a Running Driver Stack.

Protocol drivers that do not handle stack change notifications are unbound from the adapter and rebound. Bindings for protocol drivers that handle driver stack notifications successfully are not affected.

Protocol drivers should handle driver stack pause notifications. For more information about these notifications, see Pausing a Driver Stack.

Protocol drivers should handle driver stack restart notifications. For more information about these notifications, see Restarting a Driver Stack.
