This function returns the function of an intermediate driver to the context in which it was executing before it called the NdisIMSwitchToMiniportfunction.
VOID NdisIMRevertBack( IN NDIS_HANDLE MiniportAdapterHandle , IN NDIS_HANDLE SwitchHandle );
An intermediate driver should call this function as quickly as possible after a driver function makes a successful call to NdisIMSwitchToMiniport.
For example, after a successful call to NdisIMSwitchToMiniport, the Protocol XXXfunction of an NDIS intermediate driver can safely call NdisM XXXfunctions commonly called from the MiniportHandleInterruptor the MiniportTimerfunctions of underlying NIC drivers. In particular, such a Protocol XXXfunction can call NdisM XXXfunctions that indicate up to higher-level protocols bound to the intermediate driver's virtual NIC.
Until it calls this function, the execution of such a Protocol XXXfunction prevents other Miniport XXXfunctions in the same driver from running.
A call to this function without a SwitchHandlereturned by a preceding call to NdisIMSwitchToMiniportis a fatal error.
A driver that calls this function is running at IRQL DISPATCH_LEVEL.
