- * This function is called once when network device is registered.
- * 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.
- *
- * netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb,
- * struct net_device *dev);
- * Called when a packet needs to be transmitted.
- * Must return NETDEV_TX_OK , NETDEV_TX_BUSY.
- * (can also return NETDEV_TX_LOCKED iff NETIF_F_LLTX)
- * Required can not be NULL.
- *
- * u16 (*ndo_select_queue)(struct net_device *dev, struct sk_buff *skb);
- * Called to decide which queue to when device supports multiple
- * transmit queues.
- *
- * 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 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* (*ndo_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.
- *
- * void (*ndo_vlan_rx_add_vid)(struct net_device *dev, unsigned short vid);
- * If device support VLAN filtering (dev->features & NETIF_F_HW_VLAN_FILTER)
- * this function is called when a VLAN id is registered.
