When bridge loop avoidance is disabled through sysfs, the internal datastructures are not disabled, but only BLA operations are disabled. To be sure that they are removed, purge the data immediately. That is especially useful if a firmwares network state is changed, and the BLA wait periods should restart on the new network.
