[ Upstream commit fccff0862838908d21eaf956d57e09c6c189f7c5 ]
Learning is currently enabled for ports which are OVS slaves - even though OVS doesn't need this indication. Since we're not associating a fid with the port, HW would continuously notify driver of learned [& aged] MACs which would be logged as errors.
