Fixes tags in networking

I haven't done the numbers but I know that these things are true and obviously are going to affect the numbers. The networking subsystem was started enforcing that people must add a Fixes tag before other subsystems did. The second thing is that in the last few years a lot subsystems have started rebasing more. So if you fix a commit in linux-next, these days a lot of subsystems will fold the fix into the original commit instead of applying it as a separate patch. Networking doesn't rebase.

Also networking is quite big and active.
