would be nice not having to sync the if_link.h uapi header. I think it
would be even better if it can directly use the headers installed by
'make headers_install'. There was an earlier attempt to use $(KHDR_INCLUDES),
may be some of the ideas can be reused. I think there is another parallel
effort to do this also: https://lore.kernel.org/bpf/CAEf4BzaWneXBv401rOdW8ijBTqRn_Ut4FFvhbsPShh5_pjV33A@mail.gmail.com/

This uapi header improvement will probably need a separate effort/followup.
