Seems you applied it on net tree, but commit that introduced the issue
(7b9438de0cd4) is still only on net-next.
I build-tested it here before acking, it worked, on top of
4567d686f5c6d955e57a3afa1741944c1e7f4033.
Colin, please respin the patch.. add the Fixes tag, fix the missing 'o'
in my name on the changelog :-) and tag the patch as net-next tree too.
Thanks,
Marcelo
