Windows apps via wine will make use of this, and you can't just use
bind()'ing or IP_PKTINFO because the former doesn't work on broadcast
addreses and the latter might be used by the wine application at the
same time as IP_UNICAST_IF.
He explained this fully in his previous patch discussion, DO NOT repeat
this whole discussion it's a waste of time.
