[ Upstream commit ce572a5b88d5ca6737b5e23da9892792fd708ad3 ]
VF was not able to change its hardware MAC address in case the new address was already present in the MAC filter list. Change the handling of VF add mac request to not return if requested MAC address is already present on the list and check if its hardware MAC needs to be updated in this case.
