Comment 46 for bug 1711407

I've updated the patch and submitted upstream:
https://marc.info/?l=linux-netdev&m=151631015108584&w=2

The PPA also contains the latest ubuntu kernels patched for the issue, if anyone has time to test:

> How do we know when we hit the bug with your patched kernel?

I didn't include any output in the latest kernels to indicate this issue had been detected and fixed. If anyone is able to reproduce it with one of the test kernels, I can provide a debug kernel to gather more details of why it's still failing, though.
