9   RFkill integration in cfg80211 is almost invisible to drivers,
10   as cfg80211 automatically registers an rfkill instance for each
11   wireless device it knows about. Soft kill is also translated
12   into disconnecting and turning all interfaces off, drivers are
13   expected to turn off the device when all interfaces are down.
14   </p><p>
15   However, devices may have a hard RFkill line, in which case they
16   also need to interact with the rfkill subsystem, via cfg80211.
17   They can do this with a few helper functions documented here.
