Subject: ath5k: add Mesh Point support

This enables draft-802.11s Mesh Point operation.  For that we need mesh
beaconing.  Tested with AR5212/AR5213 PCI card against Zydas and b43 mesh
nodes.

Subject: ath5k: rates cleanup

cleanup the rates structures used by ath5k. instead of separate driver and
mac80211 rate structures we now setup a static ieee80211_rate array and use it
directly. no conversion between two different rate structures has to be done
any more. a lot of unused and confusing junk was deleted.

renamed ath5k_getchannels into ath5k_setup_bands because this is what it does.
rewrote it to copy the bitrates correctly for each band. this is necessary for
running different hardware with the same driver (e.g. 5211 and 5212 based
cards).

add special handling of rates for AR5211 chipsets: it uses different rate codes
for CCK rates (which are actually like the other chips but with a 0xF mask).

setup a hardware code to rate index reverse mapping table for getting the rate
index of received frames.

the rates for control frames which have to be set in
ath5k_hw_write_rate_duration are now in one single array.

Subject: ath5k: explicitly check skb->len

ieee80211_get_hdrlen_from_skb internally checks that the skb is long
enough to hold the full header, or it returns 0 if not.  The check in
ath5k does not check this case and assumes it always got the actual
header length which it then checks against the skb->len plus some headroom.

Change to ieee80211_hdrlen which always returns the hdrlen and keep the
existing headroom check.

Subject: ath5k: HW code cleanup

 * No code changes...

 * Split hw.c to multiple files for better maintenance and add some documentation on each file
   code is going to grow soon (eeprom.c for example is going to get much stuff currently developed
   on ath_info) so it's better this way.

 * Rename following functions to maintain naming scheme:

     ah_setup_xtx_desc -> ah_setup_mrr_tx_desc
     (Because xtx doesn't say much, it's actually
     a multi-rate-retry tx descriptor)

     ath5k_hw_put_tx/rx_buf - > ath5k_hw_set_tx/rxdp
     ath5k_hw_get_tx/rx_buf -> ath5k_hw_get_tx/rxdp
     (We don't put any "buf" we set descriptor pointers on hw)

     ath5k_hw_tx_start -> ath5k_hw_start_tx_dma
     ath5k_hw_start_rx -> ath5k_hw_start_rx_dma
     ath5k_hw_stop_pcu_recv -> ath5k_hw_stop_rx_pcu
     (It's easier this way to identify them, we also
     have ath5k_hw_start_rx_pcu which completes the
     set)

     ath5k_hw_set_intr -> ath5k_hw_set_imr
     (As in get_isr we set imr here, not "intr")

  * Move ath5k_hw_setup_rx_desc on ah->ah_setup_rx_desc so we can
    include support for different rx descriptors in the future

  * Further cleanups so that checkpatch doesn't complain
    (only some > 80 col warnings for eeprom.h and reg.h as usual
    due to comments)

  Tested on 5211 and 5213 cards and works ok.

Subject: cfg80211: keep track of supported interface modes

It is obviously good for userspace to know up front which
interface modes a given piece of hardware might support (even
if adding such an interface might fail later because of
concurrency issues), so let's make cfg80211 aware of that.
For good measure, disallow adding interfaces in all other
modes so drivers don't forget to announce support for one mode
when they add it.

There's really no reason for mac80211 to be using its
own interface type defines. Use the nl80211 types and
simplify the configuration code a bit: there's no need
to translate them any more now.

Subject: ath5k: Update registers and SREV ids v2

 * Update registers
 * Update SREV values and add some PHY srevs
 * Prepare ath5k.h for newer radios etc

 Thanks to Atheros 's HAL source we now know for sure how many parts we have
 and what their SREV values are. We also have some updates on registers. Prepare
 ath5k for some major updates ;-)

 My previous mail had 2 more patches following (git log misusage), sorry for double
 posting ;-(
