b43: Fix for broken transmission

This patch fixes the transmission problems introduced by
commit f04b3787bbce4567e28069a9ec97dcd804626ac7

I'm not sure if the dummy read is really required.
The old code does it. I think it can't hurt and can possibly
fix some write posting problems (hardware bugs or whatever. Who knows).

b43: Fix ofdmtab write regression

commit f04b3787bbce4567e28069a9ec97dcd804626ac7 introduced
a regression for the ofdmtable writing.

It incorrectly removed the writing of the high 16bits for
a 32bit table write and initialized the direction identifier
too late.

This patch does also some cleanups to make the code much more
readable and adds a few comments, so non rocket scientists are
also able to understand what this address caching is all about.

gianfar driver: eliminate compiler warnings and unnecessary macros

This patch eliminates the warning of unused return values when the driver
registers it sysfs files.  Now the driver will print an error if it is
unable to register the sysfs files.

It also eliminates the macros used to wrap the DEVICE_ATTR macro and the
device_create_file function call.  The macros don't reduce the number of
lines of source code in the file and the name munging makes is so that
cscope and friends don't see the references to the functions.  It's better
to just call the kernel API directly.

While we're at it, the DEVICE_ATTR instances have been moved down to
be grouped with the functions they depend on.

rt2x00: Remove redundant code in rfkill setup

In rt2x00rfkill.c, routine input_allocate_device() is called even though
input_allocate_polled_device(), which was just called, includes a call to
that routine. This patch, which has not been tested, removes the redundant code.

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.

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

Based on the patch by Mattias Nissler.

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.

* add a function to find out the size of the TLV. This is needed
