iproute2 catch up with upstream

Thanks for taking your time to report this issue and help making Ubuntu better.

The good news is that iproute2 version 4.9.0-1 has been packaged in Debian. Normally this would be synced automatically, but since the current version in Ubuntu (4.3.0-1ubuntu3) contains some additional Ubuntu-patches, it will likely need to be merged manually.

Can I help make it happen and if so where to start?

Sure :) I would start with https://wiki.ubuntu.com/UbuntuDevelopment/Merging which outlines the process with some tips for tools and workflow. I would also look a bit at the new Debian package (see https://tracker.debian.org/pkg/iproute2) and its changelog to see if the changes in Ubuntu have been included upstream or are still needed.

A fair warning; some of the patches look rather large, so if they require any changes to fit the newer version, this might not be the easiest merge to start with if you haven't done it before. :)

If you want to start on this one to help you a bit more for complex merges I'd highly recommend (in fact I use it even for trivial ones) to follow https://wiki.ubuntu.com/UbuntuDevelopment/Merging/GitWorkflow

Seems somewhat doable:
git diff old/debian | diffstat
 changelog | 58 ++++++++
 control | 4
 iproute2.install | 1
 patches/1000-ubuntu-poc-fan-driver.patch | 65 +++++++++
 patches/1001-ubuntu-poc-fan-driver-v3.patch | 133 ++++++++++++++++++
 patches/1002-ubuntu-poc-fan-driver-vxlan.patch | 177 +++++++++++++++++++++++++
 patches/1003-fix-variable-in-libnetlink.patch | 53 +++++++
 patches/series | 4
 8 files changed, 494 insertions(+), 1 deletion(-)

That helps you doing the merge as well as the reviewer of your work.
Thanks for your suggestion to volunteer for the Community!

Since major Delta seems to be for the https://wiki.ubuntu.com/FanNetworking you might want to get some help from the Kernel Team once you have something to test.

I was looking at this a bit, and the next step was to determine if we can get FanNetworking upstream. That was the plan AFAICT.

Of course, you can always maintain the delta and bring the new version, that works too :)

Thanks a bunch Jon! I see you landed 4.9.0-1ubuntu1 in Zesty. Marking Fix Released.
