		The handle returned from DigiLanInitialize.

	IN NDIS_OID Oid
		The OID (Object ID) being queried.

	IN PVOID InformationBuffer
		A buffer that will receive the information.

	IN ULONG InformationBufferLength
		The length in bytes of InformationBuffer.

	OUT PULONG BytesWritten
		The number of bytes written to InformationBuffer.

	OUT PULONG BytesNeeded
		The number of additional bytes needed to satisfy the OID.
Return Value:

	None

Description:

	DigiLanSetInformation allows other layers of the network software (e.g., a 
	transport driver) to control the miniport driver by changing information that 
	the miniport driver maintains in its OIDs, such as the packet filters or 
	multicast addresses.

Parameters:

	MiniportAdapterContext
		The handle returned from MiniportInitialize.

	Oid
		The OID. Any of the settable NDIS Global OIDs can be used. 

	pInformationBuffer
		A buffer that will receive the information.

	InformationBufferLength
		The length in bytes of InformationBuffer.

	pBytesRead
		The number of bytes read from InformationBuffer.
	
	pBytesNeeded
		The number of additional bytes needed to satisfy the OID.

Return Value:

	NDIS_STATUS_SUCCESS, or one of the following status values:
	NDIS_STATUS_INVALID_DATA
	NDIS_STATUS_INVALID_LENGTH
	NDIS_STATUS_INVALID_OID
	NDIS_STATUS_NOT_ACCEPTED
	NDIS_STATUS_NOT_SUPPORTED
	NDIS_STATUS_PENDING
	NDIS_STATUS_RESOURCES
