Header file:	Ndis.h
Windows CE versions:	2.0 and later

UINT EthNumberOfOpenFilterAddresses( IN PETH_FILTER Filter,
IN NDIS_HANDLE NdisFilterHandle );

Filter: Pointer to a previously created and initialized filter library database.
NdisFilterHandle: Handle that the filter library associates with the binding filter.

Returns the number of multicast addresses in the binding filter.

A caller must be holding the database spin lock to call this function, so the driver is running at IRQL DISPATCH_LEVEL.
