ath9k: Parse DTIM period from mac80211

With the current save power save implementation we assume a dtim period
of 1.This value is assigned based on a sanity check in the driver
eventhough we had not parsed it from mac80211.This patch obtains the actual
DTIM period from AP by parsing it from mac80211.Yet for handling
multicast traffic we may still have it as fixed rather than parsing it
from mac80211 .This does not breaks power save or anything as the sleep
duration is currently fixed in the driver.This patch may serve to improve
power save in the future by using dtim period for sleep duration and using

cfg80211/mac80211: add mesh join/leave commands

Instead of tying mesh activity to interface up,
add join and leave commands for mesh. Since we
must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured
when the device goes up.

Note that this therefore must modify mac80211 as
well since mac80211 needs to lose the logic to
start the mesh on interface up.

We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.

In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.

ath5k: Always free tx buffers before reset

 * Always free tx buffers before reset, since we also empty hw queues.
 If we don't and a queue gets stuck, we'll never decrease txq_len and sw
 will keep thinking the queue is still stuck even after reset.

mac80211: speed up AP probing using nullfunc frames

If the nullfunc frame used to probe the AP was not acked, there is no point
in waiting for the probe timeout, so advance to the next try (or disconnect)
immediately.
If we do reach the probe timeout without having received a tx status, the
connection is probably really bad and worth disconnecting.

lib: Improve EWMA efficiency by using bitshifts

Using bitshifts instead of division and multiplication should improve
performance. That requires weight and factor to be powers of two, but i think
this is something we can live with.

Thanks to Peter Zijlstra for the improved formula!

mac80211: Update last_tx_rate only for data frames

The last_tx_rate field was also updated for non-data frames that are
often sent with a lower rate (for example management frames at 1 Mbps).
This is confusing when the data rate is actually much higher.

Hence, only update the last_tx_rate field with tx rate information
gathered from last data frames.

If the rate control algorithm filled in txrc.reported_rate we don't need
to verify this information.
