Subject: Regression: Bug 196547 - Since 4.12 - bonding module not working with wireless drivers

Hi Mahesh and Andy,

James Feeney reported that there's a serious regression in bonding
module since v4.12, it doesn't work with wireless drivers anymore as
wireless drivers don't report the link speed via ethtool:

https://bugzilla.kernel.org/show_bug.cgi?id=196547

In the bug report it's said that this commit is the culprit:

3f3c278c94dd bonding: fix active-backup transition

Is there a fix for this or should that commit be reverted? This seems to
be a serious regression as there are multiple reports already and we
should get it fixed for v4.13, and the fix backported to v4.12 stable
release.
