Reading about those, it looks like they might be drop-in solutions
to implement the Linux UDP_SEGMENT and UDP_GRO socket options.
Knowing Windows however, I'm sure there's a twist somewhere...

In the hopes they work the same way, I can make the UDP_SEGMENT and
UDP_GRO socket options available in the next major Cygwin version.

Availability, probably at some point late this year. Or later.
We're not at a point where this is safe to say.

However, test versions can be made available rather soon, I think.
