The project is running into a wall due to the inability of seeing either netdevice_ops structure or hard_start_xmit function from my device driver in both Intel ixgbe and e1000e drivers. Basically, I have a structure preserving all struct net_device pointers running on system. I intend to send a skb via calling either dev->netdev_ops->ndo_start_xmit() or dev->hard_start_xmit(). Long story short, netdev_ops is a NULL pointer in my build for both ixgbe and e1000e and hard_start_xmit() is not a member function of struct net_device in 3.13.0 kernel. I borrowed the idea of calling dev_queue_xmit(skb) instead from kernel bridge driver but this is also plagued by the fact that netdev_ops does not exist, as dev_queue_xmit will subsequently use netdev_ops without guard. Are my approaches off? What did I do wrong? Does anyone have any idea as why my ixgbe and e1000e driver builds do not have netdev_ops exposed in struct net_device pointer for the hardware ports? Environment: Ubuntu 14.04 LTS with kernel version 3.13.0-66-generic Gcc 4.8 Ixgbe source version 4.0.3 e1000e source version 3.1.0.2 Thanks ahead to everyone.
