Mattias Nissler 61af43c56b rt2x00: Only update rssi average approximation on receiving beacon frames.
Restrict rssi average updating to beacon frames of the bssid the
interface is
associated with. Without this restriction, strong signals belonging to other
BSS, e.g. beacon frames coming from a nearby AP, would cause incorrectly high
rssi approximation values. This would then cause the link tuner to reduce
sensitivity, resulting in transmissions from the BSS associated to to be
missed.

Ivo van Doorn 4d8dd66c16 rt2x00: Add TX/RX frame dumping facility
This adds TX/RX frame dumping capabilities through debugfs.
The intention is that with this approach debugging of rt2x00 is
simplified since _all_ frames going in and out of the device
are send to debugfs as well along with additional information
like the hardware descriptor.

Based on the patch by Mattias Nissler.
Mattias also has some tools that will make the dumped frames
available to wireshark: http://www-user.rhrk.uni-kl.de/~nissler/rt2x00/

Larry Finger 013978b688 b43: Changes to enable BCM4311 rev 02 with wireless core revision 13
The BCM94311MCG rev 02 chip has an 802.11 core with revision 13 and
has not been supported until now. The changes include the following:

(1) Add the 802.11 rev 13 device to the ssb_device_id table to load b43.
(2) Add PHY revision 9 to the supported list.
(3) Change the 2-bit routing code for address extensions to 0b10 rather
    than the 0b01 used for the 32-bit case.
(4) Remove some magic numbers in the DMA setup.

The DMA implementation for this chip supports full 64-bit addressing with
one exception. Whenever the Descriptor Ring Buffer is in high memory, a
fatal DMA error occurs. This problem was not present in 2.6.24-rc2 due
to code to "Bias the placement of kernel pages at lower PFNs". When
commit 44048d70 reverted that code, the DMA error appeared. As a "fix",
use the GFP_DMA flag when allocating the buffer for 64-bit DMA. At present,
this problem is thought to arise from a hardware error.

This patch has been tested on my system and by Cédric Caumont
<icare40@hotmail.com>.

* add a function to search for a specific element in an IE
