+driver tries to avoid unnecessary station address reprogramming for
+controllers that use eFuse to store station address.
+The number of times that eFuse can be safely reprogrammed is 16 at
+most.
+In addition, there is no way to restore factory default station
+address once station address is reprogrammed via eFuse.
+It is highly recommended not to reprogram station address and
+it is responsibility of administrator to store original station
+address into a safe place when station address should be changed.
