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.

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/

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

This patch moves re-works the implementation of event subscription
via debugfs. For this:
* it tells cmd.c and cmdresp.c about CMD_802_11_SUBSCRIBE_EVENT
* removes lots of low-level cmd stuff from debugfs.c
* create unified functions to read/write snr, rssi, bcnmiss and
failcount
* introduces #define's for subscription event bitmask values
* add a function to search for a specific element in an IE
(a.k.a. TLV)
* add a function to find out the size of the TLV. This is needed
because lbs_prepare_and_send_command() has an argument for a
data buffer, but not for it's lengths and TLVs can be, by
definition, vary in size.
* fix a bug where it was not possible to disable an event

1) Do not reset libertas devices upon module unload. We're unloading
the module, we're not killing off devices.
2) Instead, reset libertas devices inside if_usb_disconnect, as we're
killing off interfaces and so on.
3) Resetting via disconnect callback means we no longer need to keep
track of probed libertas devices; kill off that list (and its wonderful
lack of locking..), as well.
