This patchset looks good overall (would send my Acked-by for most of

However, this is not really true. It's impossible to find out what went
wrong when you use e.g. iproute2 to configure a vxlan link.

We really need to convert the kernel log messages to the extended
netlink errors. Since you removed them prematurely, could you please
work on that?
