Hi Minh,
That is weird I can't find this patch set on group.io, and I can't apply this patch from email neither. Could you please check it?
Thanks

> When a MAC address matching interface is found, a RestEx child will be
> created to provide the Redfish communication on that interface.
> Currently, It will try to locate all RestEx binding services and choose the first
> satisfied instance without taking care about current selected interface. This
> might raise an issue on the system with multiple network devices that the
> RestEx child was installed on wrong interface.
