Yes, you will MUST do this call (like on Linux or Windows) to be able to send 
any kind of broadcast (subnet or global).

Does it mean we now MUST use setsockopt(socket, SOL_SOCKET, SO_BROADCAST, ...) 
before we can send broadcast traffic ?

Is it for sub-net broadcast or global broadcast only ?

Or is it only to filter reception on the same machine ?
