Hello,

Starting from Windows 10 version 2004, Windows supports UDP
segmentation offload and UDP receive coalescing as described in
https://docs.microsoft.com/en-us/windows-hardware/drivers/network/udp-segmentation-offload-uso-#ndis-interface-changes
and in https://docs.microsoft.com/en-us/windows/win32/winsock/ipproto-udp-socket-options
It seems that in order to support UDP segmentaion offload and UDP
receive coalescing, cygwin needs to add support for UDP_SEND_MSG_SIZE
and UDP_RECV_MAX_COALESCED_SIZE socket options for IPPROTO_UDP

Could you please add it? If so, could you please estimate when it will
be available?

Thanks you,
Rony
