Hopefully the last required fix ... disable beaconing
only on beaconing interfaces, and thus avoid calling
ieee80211_if_config for purely virtual interfaces
(those driver doesn't know about).

Before we have a probe response frame (which is used as the
beacon too) there's no need to ask drivers to beacon, they
will not get a beacon anyway.

It is rather confusing to see this in the log:
[ 695.606877] __ratelimit: 40 callbacks suppressed
[ 700.726878] __ratelimit: 40 callbacks suppressed
without ever seeing any actual message. This is because
zd1211rw doesn't compile out the net_ratelimit() call
properly if debugging is not enabled.

When a directed tim bit is set, mac80211 currently disables power save
ands sends a null frame to the AP. But if dynamic power save is
disabled, mac80211 will not enable power save ever gain. Fix this by
adding ps-poll functionality to mac80211. When a directed tim bit is
set, mac80211 sends a ps-poll frame to the AP and checks for the more
data bit in the returned data frames.
Using ps-poll is slower than waking up with null frame, but it's saves more
power in cases where the traffic is low. Userspace can control if either
ps-poll or null wakeup method is used by enabling and disabling dynamic
power save.

Currently mac80211 checks for the multicast tim bit from beacons,
disables power save and sends a null frame if the bit is set. This was
added to support ath9k. But this is a bit controversial because the AP will
send multicast frames immediately after the beacon and the time constraints
are really high. Relying mac80211 to be fast enough here might not be
reliable in all situations. And there's no need to send a null frame, AP
will send the frames immediately after the dtim beacon no matter what.
Also if dynamic power save is disabled (iwconfig wlan0 power timeout 0)
currently mac80211 disables power save whenever the multicast bit is set
but it's never enabled again after receiving the first multicast/broadcast
frame.
The current implementation is not usable on p54/stlc45xx and the
easiest way to fix this is to remove the multicast tim bit check
altogether. Handling multicast tim bit in host is rare, most of the
designs do this in firmware/hardware, so it's better not to have it in
mac80211. It's a lot better to do this in firmware/hardware, or if
that's not possible it could be done in the driver.
Also renamed the function to ieee80211_check_tim() to follow the style
of the file.
