Public bug reported: Upstream backport [3] introduced a regression with ThunderX nodes (CRB-1S, CRB-2S) and our 10G switch (Extreme Networks x670 10GE L3). We have opened a downstream bug report [1], where we temporarily bypassed this by pinning the kernel to 4.4.0-45. I also tested 4.8 (multiple builds), 4.10 and 4.11-rc1 (vanilla); all are still affected by link training issues with our switch, with 4.11-rc1 not working at all and reporting more issues (logs attached in a different LP comment [2]).
I also confirmed that reverting the commit in questions fixes the issues in our setup (tested on top of 4.10.0-13 linux-image-generic-hwe-edge package from Xenial).
