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://lore.kernel.org/netdev/20180327162419.8962-1-bl...@debian.org/
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! ** Changed in: iproute2 (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to iproute2 in Ubuntu.
