This patch makes use of the new mac80211_tx_control_flags and tx_rate to
pass Tx data, regular and 11n, from the HW tx response into the rate scaling.

This patch makes enum from the defines previously dwelled inside
ieee80211_tx_control for better readability.
The patch also addes HT flags, for 802.11n drivers:
- IEEE80211_TXCTL_OFDM_HT: request low-level driver to use HT OFDM rates
- IEEE80211_TXCTL_GREEN_FIELD: use green field protection
- IEEE80211_TXCTL_DUP_DATA: duplicate data on both 20 Mhz channels
- IEEE80211_TXCTL_40_MHZ_WIDTH: send this frame in 40Mhz width
- IEEE80211_TXCTL_SHORT_GI: send this frame with short guard interval

Tx command can be a combination of any of these flags, along with
bitrate represented by ieee80211_rate. this will allow legacy drivers to
switch easily to any 11n rate representation.

Rename the DMA ring pointers to have more descriptive and standard
names. Also remove the 6th unused TX ring. We can add it back later,
if we need it. The unused TX-status rx-ring is also removed, as that's
only used by legacy devices not supported by this driver anyway.

This is no functional change, except less memory allocation for
the removed rings.

Make some changes which mimic what we see in register dumps.
This patch does not add a helper to ath5k_hw_reset(). It
does seem clear we need a re-shuffle around ath5k_hw_reset()
though as code in there is lengthy and already hitting 80-char
limit. This can be dealt with later though.

 * Since RF2413 it seems that RF_BUFFER settings are different (notice
that the last part -"bank 7" or whatever- is smaller than in 5111/5112).
So until we know what's going on we assume there is no gain optimization

The previously unused CR_CAM_MODE register is set to MODE_AP_WDS. This makes the
driver ack mesh (WDS) frames. It does not affect Infra functionality of the
driver.

Previously missing beaconing support has been added. This might also help
implement a currently missing ah-hoc mode.

Support for interrupts from the device have been added, but we are not handling
most of them.

Mesh interfaces are considered associated as long as the interface is up.

Today I hit one of my new WARN_ONs in the mac80211 code because
a key wasn't being freed correctly. After wondering for a while

on that list, not just for default keys. This patch fixes that.

I noticed a bug I introduced when mesh is enabled: sta_info_destroy()
will end up calling cancel_timer() on a timer that has never been
initialized because the timer is only initialized in mesh_plink_alloc(),
not in sta_info_alloc(). This patch moves the initialization of all mesh
related fields into sta_info_alloc(), adds a bit of sanity checking to
the cfg80211 handlers and sta_info_insert() and makes mesh_plink_alloc()
a static helper function that is only used from the mesh plink code.

Quite a while ago I started this book. The required kernel-doc
patches have since gone into the tree so it is now possible to
build the book in mainline.

The actual documentation is still rather incomplete and not all
things are linked into the book, but this enables us to edit
the documentation collaboratively, hopefully driver authors can
add documentation based on their experience with mac80211.
