Porting Virtual Miniport Halt Operations to NDIS 6.0

  • Artículo

Like NDIS 5.x intermediate drivers, NDIS 6.0 intermediate drivers usually halt virtual miniports during the unbind operation. In NDIS 6.0, the ProtocolUnbindAdapterEx function replaces the NDIS 5.xProtocolUnbindAdapter function.

To halt a virtual miniport, NDIS 5.x calls the intermediate driver's MiniportHalt function. In NDIS 6.0, the MiniportHaltEx function replaces MiniportHalt.

If an NDIS 6.0 intermediate driver calls the NdisIMDeInitializeDeviceInstance function, NDIS calls the MiniportHaltEx function for the affected virtual miniport. An intermediate driver usually calls NdisIMDeInitializeDeviceInstance from its ProtocolUnbindAdapterEx function.

NDIS 6.0 filter drivers do not require a virtual miniport. For more information about filter drivers, see NDIS 6.0 Filter Drivers.
