It will be pushed if I get no objections before 02/13/20. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Thanks.

We cannot make link status to change from down to up by interrupt callback. So we need to wait for the controller to acquire link when ports start. Through multiple tests, 5s should be enough.
