+ * is mostly defined in the cross-platform nsWifiMonitor.cpp. This function
+ * is implemented in various platform-specific files but the implementation
+ * is almost identical in each file. We relegate the Windows-specific
+ * work to the `WinWifiScanner` class and deal with non-Windows-specific
+ * issues like calling listeners here. Hopefully this file can be merged
+ * with the other implementations of `nsWifiMonitor::DoScan` since a lot
