+Subject: [PATCH] bonding: ratelimit failed speed/duplex update warning
+
+bond_miimon_commit() handles the UP transition for each slave of a bond
+in the case of MII. It is triggered 10 times per second for the default
+MII Polling interval of 100ms. For device drivers that do not implement
+__ethtool_get_link_ksettings() the call to bond_update_speed_duplex()
+fails persistently while the MII status could remain UP. That is, in
+this and other cases where the speed/duplex update keeps failing over a
+longer period of time while the MII state is UP, a warning is printed
+every MII polling interval.
+
+To address these excessive warnings net_ratelimit() should be used.
+Printing a warning once would not be sufficient since the call to
+bond_update_speed_duplex() could recover to succeed and fail again
+later. In that case there would be no new indication what went wrong.
+

+Subject: [PATCH] bonding: require speed/duplex only for 802.3ad, alb and tlb
+
+The patch c4adfc822bf5 ("bonding: make speed, duplex setting consistent
+with link state") puts the link state to down if
+bond_update_speed_duplex() cannot retrieve speed and duplex settings.
+Assumably the patch was written with 802.3ad mode in mind which relies
+on link speed/duplex settings. For other modes like active-backup these
+settings are not required. Thus, only for these other modes, this patch
+reintroduces support for slaves that do not support reporting speed or
+duplex such as wireless devices. This fixes the regression reported in
+bug 196547 (https://bugzilla.kernel.org/show_bug.cgi?id=196547).
+
+Fixes: c4adfc822bf5 ("bonding: make speed, duplex setting consistent
+with link state")
