I found two different articles on microsoft.com which confirms that SO_SNDBUF=0 is valid and is intended to completely disable kernel buffering:
* https://support.microsoft.com/en-gb/help/181611/socket-overlapped-i-o-versus-blocking-nonblocking-mode
* https://blogs.msdn.microsoft.com/larryosterman/2004/08/06/the-consequences-of-ignoring-nagling-and-delayed-acks/

"If SO_SNDBUF=0, each send() or WriteFile() must wait for an acknowledgement from the other side before returning. (That is the only way for the protocol to implement retransmissions)"
