Hi, XQUIC can complete handshake with quic-go in interoperability testing, see https://interop.seemann.io/ for more details.

Hi, Quic-go response an address-validation retry frame, the format is: |longheader|packet type|version|dcid len|dcid|scid len|scid|token|integrity tag|

But from xqc_packet_parse_retry, it seems xquic hope following format: |longheader|packet type|version|dcid len|dcid|scid len|scid|odcid|

Which leads to retry frame parse failed.
