[ Upstream commit 72110b567479f0282489a9b3747e76d8c67d75f5 ]
When set 2 same MAC to different function of one port, IMP will return error as the later one may modify the origin one. This will cause bond fail for 2 VFs of one port.
Driver just print warning and return 0 with this patch, so if set same MAC address, it will return 0 but do not really configure HW.
