I've done more testing around enabling IFLA_IF_NETNSID for RTM_NEWLINK
as well and I think that the change is actually trivial. However, I
would like to wait before sending this patch out until we have agreed on
the patches for RTM_SETLINK and RTM_DELLINK in this series. Once we have
merged those I can just send another small commit. Or - if changes to
this patch series are required - I can just add it in a v2.

Thanks
Christian
