If NAN interface is created with NL80211_ATTR_SOCKET_OWNER, the socket that is used to create the interface is used for all NAN operations and reporting NAN events. However, it turns out that sending commands and receiving events on the same socket is not possible in a completely race-free way: If the socket buffer is overflowed by the events, the command response will not be sent. In that case the caller will block forever on recv. Using non-blocking socket for commands is more complicated and still the command response or ack may not be received. So, keep unicasting NAN events to the interface creator, but allow using a different socket for commands.
