Bug report

Bug description:

import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_QUICKACK, 1)
sock.getsockopt(socket.IPPROTO_TCP, socket.TCP_QUICKACK)

On windows this throws AttributeError: module 'socket' has no attribute 'TCP_QUICKACK'

Support is for this setting is available on windows, it just isn't implemented in the python runtime. It's implemented for Linux and I believe for Mac as well, though I didn't check the latter.

I'm opening this mostly to track my PR as I already have the fix implemented.

CPython versions tested on:

3.12, CPython main branch

Operating systems tested on:

Linux, Windows
