I emailed the patch series to the list. There is a a "[PATCH net-next
0/4] tcp: mitigate TCP ACK loops due to out-of-window validation
dupacks" cover letter with an overview. And you can find the patches
here:

http://patchwork.ozlabs.org/patch/437463/
http://patchwork.ozlabs.org/patch/437464/

Please feel free to try these out and let us know how they work for you.
