I noticed that this series was marked "RFC" in patchwork. I consider this series
ready to apply. I am requesting *testing*, in particular on 10gec/dtsec boards
(P-series). Since no one seems to have tried that over the past 4 months that
I've been working on this series, perhaps the best way for it to get tested is
to apply it...
