2559 * WARNING: DO NOT COPY THIS CODE INTO YOUR APPLICATION
2560 *
2561 * This code has a bug, which requires creating a separate
2562 * nl80211 socket to fix:
2563 * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or
2564 * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel
2565 * before (!) we listen to it, because we only start listening
2566 * after we send our scan request.
2567 *
2568 * Doing it the other way around has a race condition as well,
2569 * if you first open the events socket you may get a notification
2570 * for a previous scan.
2571 *
2572 * The only proper way to fix this would be to listen to events
2573 * before sending the command, and for the kernel to send the
2574 * scan request along with the event, so that you can match up
2575 * whether the scan you requested was finished or aborted (this
2576 * may result in processing a scan that another application
2577 * requested, but that doesn't seem to be a problem).
2578 *
2579 * Alas, the kernel doesn't do that (yet).
