Hi Lorenzo, Thanks for the review. Do we need a flag to control statically added MACs from CMS vs dynamically learnt MAC from pinctrl for a given IP?
Typically static configurations for a MAC Table override dynamically learnt MACs. In this patch even if pinctrl learns a different MAC for the given IP, statically configured MAC will eventually be programmed.
