downstream_socket_config
  (:ref:`config.core.v3.UdpSocketConfig <envoy_v3_api_msg_config.core.v3.UdpSocketConfig>`) UDP socket configuration for the listener. The default for
  :ref:`prefer_gro <envoy_v3_api_field_config.core.v3.UdpSocketConfig.prefer_gro>` is false for
  listener sockets. If receiving a large amount of datagrams from a small number of sources, it
  may be worthwhile to enable this option after performance testing.
