4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Yuval Mintz <yuvalm@xxxxxxxxxxxx> [ 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.
