This patchset adds a new netdevice feature to toggle RX offloads of
UDP-based tunnel via ethtool. This is useful if the offload is causing
issues, for example if the hardware is buggy.
The feature is added to all devices providing the ->ndo_udp_tunnel_add
op, and enabled by default to preserve current behavior.
When the administrator disables this feature on a device, all
currently offloaded ports are cleared from the device. When the
feature is turned on, the stack notifies the device about all current
ports.
v2:
- rename feature bit to NETIF_F_RX_UDP_TUNNEL_PORT
- rename ethtool feature to rx-udp_tunnel-port-offload
