I think this patch still makes sense for 'net-next' as cleanup. Just explain it
correctly in the log. It's not needed for 'net'.
As far as stable for 3.15, I'm not yet sure what exactly the problem
you're hitting. The way you describe it, the whole ppp filtering shouldn't
be working in 3.15...

Also it sounds like you've created a patch out of 3.15 tree, but marked it
as 'net-next'. That's not the right. If the tag is 'net-next' it obviously
should be based on net-next tree.
