+ *     The network device can use this to any late stage initializaton
+ *     or semantic validattion. It can fail with an error code which will
+ *     be propogated back to register_netdev
+ *
+ * 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.
+ *
+ * int (*ndo_open)(struct net_device *dev);
+ *     This function is called when network device transistions to the up
+ *     state.
+ *
+ * int (*ndo_stop)(struct net_device *dev);
+ *     This function is called when network device transistions to the down
+ *     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);
+ *      This function is called device changes address list filtering.
+ *
+ * void (*ndo_set_multicast_list)(struct net_device *dev);
+ *      This function is called when the multicast address list changes.
+ *
+ * int (*ndo_set_mac_address)(struct net_device *dev, void *addr);
+ *      This function  is called when the Media Access Control address
+ *      needs to be changed. If not this interface is not defined, the
+ *      mac address can not be changed.
+ *
+ * int (*ndo_validate_addr)(struct net_device *dev);
+ *      Test if Media Access Control address is valid for the device.

+ * int (*ndo_do_ioctl)(struct net_device *dev, struct ifreq *ifr, int cmd);
+ *      Called when a user request an ioctl which can't be handled by
+ *      the generic interface code. If not defined ioctl's return
+ *      not supported error code.
+ *
+ * int (*ndo_set_config)(struct net_device *dev, struct ifmap *map);
+ *      Used to set network devices bus interface parameters. This interface
+ *      is retained for legacy reason, new devices should use the bus
+ *      interface (PCI) for low level management.
+ *
+ * int (*ndo_change_mtu)(struct net_device *dev, int new_mtu);
+ *      Called when a user wants to change the Maximum Transfer Unit
+ *      of a device. If not defined, any request to change MTU will
+ *      will return an error.
+ *
+ * void (*ndo_tx_timeout) (struct net_device *dev);
+ *      Callback uses when the transmitter has not made any progress
+ *      for dev->watchdog ticks.
+ *
+ * struct net_device_stats* (*get_stats)(struct net_device *dev);
+ *      Called when a user wants to get the network device usage
+ *      statistics. If not defined, the counters in dev->stats will
+ *      be used.
+ *
+ * void (*ndo_vlan_rx_register)(struct net_device *dev, struct vlan_group *grp);
+ *      If device support VLAN receive accleration
+ *      (ie. dev->features & NETIF_F_HW_VLAN_RX), then this function is called
+ *      when vlan groups for the device changes.  Note: grp is NULL
+ *      if no vlan's groups are being used.
