+Subject: [PATCH] bridge: allow setting hash_max + multicast_router if
+ interface is down
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Network managers like netifd (used in OpenWRT for instance) try to
+configure interface options after creation but before setting the
+interface up.
+
+Unfortunately the sysfs / bridge currently only allows to configure the
+hash_max and multicast_router options when the bridge interface is up.
+But since br_multicast_init() doesn't start any timers and only sets
+default values and initializes timers it should be save to reconfigure
+the default values after that, before things actually get active after
+the bridge is set up.
