VOID fddiUndoChangeFilterLongAddresses( IN PFDDI_FILTER Filter ); Routine Description: The ChangeFilterAddress routine will call an action routine when the overall multicast address list for the adapter has changed. If the action routine returns a value other than pending or success then this routine has no effect on the multicast address list for the open or for the adapter as a whole. NOTE: THIS ROUTINE ASSUMES THAT THE LOCK IS HELD. Arguments: Filter - A pointer to the filter database. NdisFilterHandle - Pointer to the open. NdisRequest - If it is necessary to call the action routine, this will be passed to it. AddressCount - The number of elements (addresses, not bytes) in MulticastAddressList. Addresses - The new multicast address list for this binding. This is a sequence of FDDI_LENGTH_OF_LONG_ADDRESS byte addresses, with no padding between them. Set - A boolean that determines whether the multicast addresses are being adjusted due to a set or because of a close. (The filtering routines don't care, the MAC might.) Return Value: If it calls the action routine then it will return the status returned by the action routine. If the status returned by the action routine is anything other than NDIS_STATUS_SUCCESS or NDIS_STATUS_PENDING the filter database will be returned to the state it was in upon entrance to this routine. If the action routine is not called this routine will return the following statum: NDIS_STATUS_SUCCESS - If the new packet filters doesn't change the combined mask of all bindings packet filters.
