I've already reviewed / commented on previous versions of this patch
and am hoping for comments from a wider audience.

I'm hoping this relatively generic and easily extensible way of
exposing additional per-packet metadata to userspace catches on.
Something similar would also be useful for tcpdump (ie. raw packet sockets).

I'd rather people build generic infrastructure for this.

We already have a META match in the packet scheduler, and all sorts
of BPF extensions which provide SKB metadata too.  That's the right
approach, something more generic.

Therefore, putting a custom version of SKB metadata export into the
TUN driver makes absolutely no sense to me.

I'm not applying this, sorry.
