Feature Request: Ethernet information from cnMeaestor REST API

We use the cnMaestro REST API to generate reports across all APs. We would like to get ethernet negotiated rate and error stats via the REST API, but this does not seem to be available.
api devices/{mac}/statistics give detailed information about wifi events, but no ethernet info.

In addition using the Maestro cloud controller, devices/{mac}/statistics has two fields which are null on all tested APs

Having ethernet negotiated rate and error statistics available by REST API would help us better maintain the quality of our system.
