Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet Equipment Clock (EEC) and have the ability to recover synchronization from the synchronization inputs - either traffic interfaces or external frequency sources. The EEC can synchronize its frequency (syntonize) to any of those sources. It is also able to select synchronization source through priority tables and synchronization status messaging. It also provides neccessary filtering and holdover capabilities This patch series introduces basic interface for reading the Ethernet Equipment Clock (EEC) state on a SyncE capable device. This state gives information about the source of the syntonization signal and the state of EEC. This interface is required to implement Synchronization Status Messaging on upper layers.
