Re: [PATCH v2 0/2] MR6335: winsock: Support IPV4 UDP broadcast on connected socket without SO_BROADCAST.

Yes, it is undocumented as far as I can tell but probably not accidental neither on Windows nor on Linux. connect() on UDP socket does something, apparently in particular pre-checking destination address.
