dispatch - FwpmEngineOpen fails at dispatch level

Question

I am trying to add a WFP filter while holding an NDIS RW lock, but FwpmEngineOpen or FwpmTransactionBegin functions fail. Is there a limitation that prevents these functions to work at Dispatch level?

Thanks!

FwpmEngineOpen0のドキュメントには、要件は IRQL == PASSIVE_LEVEL であると記載されているため、DISPATCH_LEVEL では機能しません。
