Let me just say once again that all this discussion is entirely
orthogonal to properly supporting suspend/resume in mac80211, it's
always possible for userspace to do anything with the devices before
going into suspend, but the kernel should take some care to resume as it
was at suspend time, which is what we're aiming for here. Of course,
this may mean that at resume we lose the AP connection that we think we
still have right away, but that's great since then wpa_supplicant will
reconnect quickly.
