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. -- Kalle Valo
