+Subject: [PATCH] net: switchdev: do not propagate bridge updates across
+ bridges
+
+When configuring a tree of independent bridges, propagating changes
+from the upper bridge across a bridge master to the lower bridge
+ports brings surprises.
+
+For example, a lower bridge may have vlan filtering enabled.  It
+may have a vlan interface attached to the bridge master, which may
+then be incorporated into another bridge.  As soon as the lower
+bridge vlan interface is attached to the upper bridge, the lower
+bridge has vlan filtering disabled.
+
+This occurs because switchdev recursively applies its changes to
+all lower devices no matter what.
