Most wireless drivers load their firmware at interface open time, which
generally occurs after the filesystem is available. However, the ipw drivers
load their firmware at probe time because firmware is required to read the
device MAC address. When built-in, probe happens before the filesystem is
available, hence device init will only complete successfully if the user
has made special arrangements (including firmware plus a loader in the
initramfs).

Cleanup after API changes patch (checkpatch.pl stuff) and on
ath5k_hw_channel() make use of the existing ath5k_channel_ok()
instead of re-implementing the checks again. This was necessary
to make the code cleaner and fit the 80-chars wide limit so
sending it within the same patch.
Finally make a note that we *may* eventually move cap_range stuff
to struct wiphy (band frequency range capabilities). This
information can later be exported to userspace, for example,
and giving it access to mac80211 and drivers in general can come
in handy.

Tested on 5211, 5213+5112, 5213A+2112A and it wors fine.
Also i figured out a way to process rate vallue found
on status descriptors, it's still buggy but we are getting
closer (i think it improved stability a little).

This patch creates new cfg80211 wiphy API for channel and bitrate
registration and converts mac80211 and drivers to the new API. The
old mac80211 API is completely ripped out. All drivers (except ath5k)
are updated to the new API, in many cases I expect that optimisations
can be done.
Along with the regulatory code I've also ripped out the
IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be
unnecessary if the hardware simply gives us whatever channels it wants
to support and we then enable/disable them as required, which is pretty
much required for travelling.
Additionally, the patch adds proper "basic" rate handling for STA
mode interface, AP mode interface will have to have new API added
to allow userspace to set the basic rate set, currently it'll be
empty... However, the basic rate handling will need to be moved to
the BSS conf stuff.
I do expect there to be bugs in this, especially wrt. transmit
power handling where I'm basically clueless about how it should work.

As Johannes Berg indicated the BEACON and AFTER_BEACON
queue indeces in mac80211 should be removed because they
are too hardware specific. This patch adds the queue index
defines into rt2x00queue.h and removes the dependency of
the defines inside mac80211.h.
Also move rt2x00pci_beacon_update() into rt2400pci and
rt2500pci individually since it is no longer a generic
function since rt61 and rt2800 no longer use that.

Rework the interface handling. Delete the interface structure
and replace it with a per-interface structure. This changes the
way rt2x00 handles the active interface drastically.
Copy ieee80211_bss_conf to the this rt2x00_intf structure during
the bss_info_changed() callback function. This will allow us to
reference it later, and removes the requirement for the device flag
SHORT_PREAMBLE flag which is interface specific.
Drivers receive the option to give the maximum number of virtual
interfaces the device can handle. Virtual interface support:
rt2400pci: 1 sta or 1 ap, * monitor interfaces
rt2500pci: 1 sta or 1 ap, * monitor interfaces
rt2500usb: 1 sta or 1 ap, * monitor interfaces
rt61pci: 1 sta or 4 ap, * monitor interfaces
rt73usb: 1 sta or 4 ap, * monitor interfaces
At the moment none of the drivers support AP and STA interfaces
simultaneously, this is a hardware limitation so future support
will be very unlikely.
Each interface structure receives its dedicated beacon entry,
with this we can easily work with beaconing while multiple master
mode interfaces are currently active.
The configuration handlers for the MAC, BSSID and type are
often called together since they all belong to the interface
configuration. Merge the 3 configuration calls and cleanup
the API between rt2x00lib and the drivers. While we are cleaning
up the interface configuration anyway, we might as well clean up
the configuration handler as well.

The driver should select what CRC algorithm is required
when performing a checksum on the firmware.
rt61pci & rt73usb require crc-itu-t
rt2800pci & rt2800usb require crc-ccitt
Legacy 2800pci/usb driver uses crc-itu-t + bit order reversion,
but that is just inefficient especially since the end result is
the same as a different algorithm which is also available as library. ;)

This will enable the creation of master mode and adhoc
interfaces again. This does not mean the issues surrounding
beaconing have been resolved, but this will make testing
easier and perhaps we can discover which cards are actually
working and which ones not.

This introduces a big queue handling overhaul, this also
renames "ring" to "queues".
Move queue handling into rt2x00queue.c and the matching header,
use Kerneldoc to improve rt2x00 library documentation.
Access to the queues is now protected under a spinlock, this
to prevent race conditions which could corrupt the indexing
system of the queue.
Each queue entry allocates x bytes for driver/device specific data,
this cleans up the queue structure significantly and improves
code readability.
rt2500usb no longer needs 2 entries in the beacon queue to correctly
send out the guardian byte. This is now handled in the entry specific
structure.
rt61 and rt73 now use the correct descriptor size for beacon frames,
since this data is written into the registers not the entire TXD
descriptor was used but instead of a subset of it named TXINFO.
Finally this also fixes numerous other bugs related to incorrect
beacon handling or beacon related code.
