Are these available anywhere? Or could they be made available? This seems like a much better solution than disabling timestamps.Neal is currently polishing a serie of 4 patches. This should be land to netdev shortly ;)
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/437462/ http://patchwork.ozlabs.org/patch/437463/ http://patchwork.ozlabs.org/patch/437464/ http://patchwork.ozlabs.org/patch/437465/ Please feel free to try these out and let us know how they work for you.
