  "udp_packet_packet_writer_config": {...}
}

downstream_socket_config: (config.core.v3.UdpSocketConfig) UDP socket configuration for the listener. The default for 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.

quic_options: (config.listener.v3.QuicProtocolOptions) Configuration for QUIC protocol. If empty, QUIC will not be enabled on this listener. Set to the default object to enable QUIC without modifying any additional options.

udp_packet_packet_writer_config

(config.core.v3.TypedExtensionConfig) Configuration for the UDP packet writer. If empty, HTTP/3 will use GSO if available (UdpDefaultWriterFactory) or the default kernel sendmsg if not, (UdpDefaultWriterFactory) and raw UDP will use kernel sendmsg.
