Depending on the udp service, it can reply with some udp data. In that case ovn-controller will warn with next message:
pinctrl(ovn_pinctrl0)|WARN|handle service check: Unsupported protocol - [11] With this patch ovn-controller ignores UDP packets, which came to pinctrl_handle_svc_check(). This is not something abnormal, so don't write warnings.
