453 * The network device can use this to any late stage initializaton
454 * or semantic validattion. It can fail with an error code which will
455 * be propogated back to register_netdev
456 *
457 * void (*ndo_uninit)(struct net_device *dev);
458 * This function is called when device is unregistered or when registration
459 * fails. It is not called if init fails.
460 *
461 * int (*ndo_open)(struct net_device *dev);
462 * This function is called when network device transistions to the up
463 * state.
464 *
465 * int (*ndo_stop)(struct net_device *dev);
466 * This function is called when network device transistions to the down
467 * state.
468 *
469 * int (*ndo_hard_start_xmit)(struct sk_buff *skb, struct net_device *dev);
470 * Called when a packet needs to be transmitted.
471 * Must return NETDEV_TX_OK , NETDEV_TX_BUSY, or NETDEV_TX_LOCKED,
472 * Required can not be NULL.
473 *
474 * u16 (*ndo_select_queue)(struct net_device *dev, struct sk_buff *skb);
475 * Called to decide which queue to when device supports multiple
476 * transmit queues.
477 *
478 * void (*ndo_change_rx_flags)(struct net_device *dev, int flags);

480 * changes to configuration when multicast or promiscious is enabled.
481 *
482 * void (*ndo_set_rx_mode)(struct net_device *dev);
483 * This function is called device changes address list filtering.
484 *
485 * void (*ndo_set_multicast_list)(struct net_device *dev);
486 * This function is called when the multicast address list changes.
487 *

490 * needs to be changed. If not this interface is not defined, the

499 * not supported error code.
500 *
501 * int (*ndo_set_config)(struct net_device *dev, struct ifmap *map);
502 * Used to set network devices bus interface parameters. This interface
503 * is retained for legacy reason, new devices should use the bus
504 * interface (PCI) for low level management.
505 *
506 * int (*ndo_change_mtu)(struct net_device *dev, int new_mtu);
507 * Called when a user wants to change the Maximum Transfer Unit
508 * of a device. If not defined, any request to change MTU will
509 * will return an error.
510 *
511 * void (*ndo_tx_timeout)(struct net_device *dev);
