Comment 4 for bug 1856045

Well this is a consequence of this upstream change in iproute2: https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/commit/?h=v4.16.0&id=ba2fc55b99f8363c80ce36681bc1ec97690b66f5. Upstream discussion, such as it is, of the patch appears to be here: https://<email address hidden>/

Probably the next step is to email the netdev list about this. Is that something you would be interested in doing? You are probably better able to explain your use case than I am!
