UDP隧道Offload
对于支持UDP隧道(VXLAN/GENEVE)Offloading功能的物理网卡,其通过标志位NETDEV_UDP_TUNNEL_PUSH_INFO/NETDEV_UDP_TUNNEL_DROP_INFO进行表示。函数udp_tunnel_push_rx_port与udp_tunnel_drop_rx_port用于设置和取消网卡的Offloading功能。
void udp_tunnel_push_rx_port(struct net_device *dev, struct socket *sock, unsigned short type) { struct sock *sk = sock->sk; struct udp_tunnel_info ti; if (!dev->netdev_ops->ndo_udp_tunnel_add || !(dev->features & NETIF_F_RX_UDP_TUNNEL_PORT)) return; ti.type = type; ti.sa_family = sk->sk_family; ti.port = inet_sk(sk)->inet_sport; dev->netdev_ops->ndo_udp_tunnel_add(dev, &ti); } EXPORT_SYMBOL_GPL(udp_tunnel_push_rx_port); void udp_tunnel_drop_rx_port(struct net_device *dev, struct socket *sock, unsigned short type) { struct sock *sk = sock->sk; struct udp_tunnel_info ti; if (!dev->netdev_ops->ndo_udp_tunnel_del || !(dev->features & NETIF_F_RX_UDP_TUNNEL_PORT)) return; ti.type = type; ti.sa_family = sk->sk_family; ti.port = inet_sk(sk)->inet_sport; dev->netdev_ops->ndo_udp_tunnel_del(dev, &ti); }
