bonding: don't use stale speed and duplex information

[Nicolas Dichtel]

This upstream patch is missing (needed for all kernel between 3.9 and 4.4 (both included)):

266b495f11d6 bonding: don't use stale speed and duplex information
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=266b495f11d6

Without this patch, reported speeds can be wrong.

I built a vivid and Xenial test kernel with the patch. The test kernels can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1646068/vivid/
http://kernel.ubuntu.com/~jsalisbury/lp1646068/xenial

The patch needed a minor backport to apply to Xenial. Vivid needed the same backport of the patch, but also required commit 69a2338 as a prerequisite.

Trusty on the other hand requires quite a few prerequisite commits for the patch to apply cleanly. I'm still working to identify all the prereqs.

Could you test the Vivid an Xenial test kernels to see if the resolve the bug. I'll post an update when the Trusty test kernel is ready.

[Nicolas Dichtel (nicolas-dichtel)]

The bug has been seen by one of our client and the patch has fixed the problem for them, but we never succeed to reproduce the problem. The commitlog of the patch also confirms the analysis.

[Joseph Salisbury (jsalisbury)]

Thanks for the update, Nicholas. Did the client confirm the vivid or xenial test kernel resolves the bug, or maybe both?

[Joseph Salisbury (jsalisbury)]

There is now a Trusty test kernel available as well. It can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1646068/trusty

[Vincent JARDIN (vincent-jardin)]

They build their own kernel, they cannot test your http://kernel.ubuntu.com/~jsalisbury/lp1646068/trusty

From the code review, this fix is needed.
