+ *
+ * void (*ndo_uninit)(struct net_device *dev);
+ * This function is called when device is unregistered or when registration
+ * fails. It is not called if init fails.

+ * state.
+ *

+ * state.
+ *
+ * void (*ndo_change_rx_flags)(struct net_device *dev, int flags);
+ * This function is called to allow device receiver to make
+ * changes to configuration when multicast or promiscious is enabled.
+ *
+ * void (*ndo_set_rx_mode)(struct net_device *dev);
