+Subject: [PATCH 079/165] dummy: Add ndo_uninit().
+
+commit 890fdf2a0cb88202d1427589db2cf29c1bdd3c1d upstream.
+
+In register_netdevice(), when ndo_init() is successful and later
+some error occurred, ndo_uninit() will be called.
+So dummy deivce is desirable to implement ndo_uninit() method
+to free percpu stats for this case.
+And, ndo_uninit() is also called along with dev->destructor() when
+device is unregistered, so in order to prevent dev->dstats from
+being freed twice, dev->destructor is modified to free_netdev().
