rt2x00: Rate structure overhaul
Recent changes to the rate structure registration broke rt2x00,
the hw_value was reduced from 32bits to 16bits while rt2x00 used
the full 32bits. However the way rt2x00 used the value was inflexible
and needed to be changed anyway.
This patch creates a array containing information for each rate,
the hw_value passed to mac80211 is the index value for that array
including a field to indicate if short preamble should be enabled.

cfg80211 API for channels/bitrates, mac80211 and driver conversion
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.

rt2x00: Add per-interface structure
Rework the interface handling. Delete the interface structure

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.

rt2x00: Queue handling overhaul
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.

[BNX2X]: Correct Link management
Properly protect PHY access between two devices on the same board with
a HW lock.
Use GPIO to clear all previous configurations before changing link
parameters.
Shut down the external PHY in case of fan failure.
Reducing the MDC/MDIO clock to 2.5MHz due to problems with some
devices.
Resolve the flow control response according to autoneg with external
PHY.
Unmasking all PHY interrupts in single write to prevent a race in the
interrupts order.
LASI indication fixes to work with peculiarities of PHYs.
Disable MAC RX to avoid a HW bug when closing the MAC under traffic.
Disable parallel detection on HiGig due to HW limitation.
Updating the shared memory structure to work with the current
bootcode.

[IPCOMP]: Disable BH on output when using shared tfm
Because we use shared tfm objects in order to conserve memory,
(each tfm requires 128K of vmalloc memory), BH needs to be turned
off on output as that can occur in process context.
Previously this was done implicitly by the xfrm output code.
That was lost when it became lockless. So we need to add the
BH disabling to IPComp directly.
