I'm not sure it's worth adding an extra file just for this enum and the two
functions below. Maybe put it all in filtering_network_manager.h?

I need this in both EmptyNetworkManager as well as FilteringNetworkManager

Yes, my suggestion was to include filtering_network_manager from
empty_network_manager. But feel free to keep it as is.

maybe calle it ReportTimeToUpdateNetworkList()

Done.
