var MaxFragSize = 1200 - PacketOverHead - 3

MaxFragSize is a safe udp relay packet size because tuicv5 support udp fragment so we unneeded to do a magic modify for quic-go to increase MaxDatagramFrameSize it may not work fine in some platform "1200" from quic-go's MaxDatagramSize "-3" from quic-go's DatagramFrame.MaxDataLen
