Backport recent bbr bugfixes to 4.10 kernel

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1708604

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Please backport these tcp_bbr patches to ubuntu-zesty 4.10 kernel. These patches have already landed in linux-stable kernels in 4.9.42 and 4.12.6.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-zesty' to 'verification-done-zesty'. If the problem still exists, change the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I'm setting the Xenial task to invalid, since these patches are only for 4.10. Xenial/hwe kernel will get these patches automatically.

Hi @savetherbtz,

Could you please verify the fix with the Zesty kernel currently in -proposed?

Thank you!

Sadly, we've already workedaround that problem with a custom-built module. Let me see if my colleagues can test the kernel.
