Disable TX IP/TCP/UDP checksum offloading for RTL8168C/RTL8168CP. Previously only TX IP checksum offloading was disabled but it's reported that TX checksum offloading for UDP datagrams with IP options also generates corrupted frames. Reporter's controller is RTL8168CP but I guess RTL8168C also have the same issue since it shall share the same core.
