The reported TX power level is calculated from the

libertas: add asynchronous firmware loading capability
As described at
http://article.gmane.org/gmane.linux.kernel.wireless.general/86084
libertas is taking a long time to load because it loads firmware
during module loading.
Add a new API for interface drivers to load their firmware
asynchronously. The same semantics of the firmware table are followed
like before.
Interface drivers will be converted in follow-up patches, then we can
remove the old, synchronous firmware loading function.

Remove the ability to pass module parameters with firmware filenames
for USB and SDIO interfaces.
Remove the ability to pass custom "user" filenames to lbs_get_firmware().
Remove the ability to reprogram internal device memory with a different
firmware from the USB driver (we don't know of any users), and simplify
the OLPC firmware loading quirk to simply placing the OLPC firmware
at the top of the list (we don't know of any users other than OLPC).
Move lbs_get_firmware() into its own file.

rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe fails
There are connection stalls or very poor throughputs with rt2800
hardware using 802.11n in AP mode since patch "mac80211: retry sending
failed BAR frames later instead of tearing down aggr"[1][2].
Since rt2800 hardware is not able to correctly report the tx status of
BAR frames, this patch removes as workaround the existing error handling
on AP side, which lets mac80211 send a BAR when an AMPDU subframe fails.
As a result, most wifi clients (aside from Intel STAs on Windows)
instead will timeout now the reorder buffer and request the lost frame
again.
The correct solution would be, to tear down BA session on AP side.
This patch was born on the basis of "[RFT] rt2x00: Tear down BA
session on QoS frame failure"[3].

mac80211: Take into account TSF adjustment latency in Toffset setpoint
When testing mesh synchronization we observed a global TSF slowdown that
was dependent on the number of synchronized mesh stations. This seems
to be caused by the TSF adjustment (read/write) latency.
Adding a small margin to the Toffset setpoint solved the problem.
