This patch hopefully contains all necessary changes to support
firmwares for all devices up to atleast 2.13.3.0.
(or: LowerMAC Protocol Rev: 5.5 )
And this is a big win, since:
* newer firmwares are more stable and reliable than the old ones.
* no problems anymore with packages > 1399 octets (without lowering the MTU).
* monitor mode finally works on USB for more than just a few seconds.

* 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)

This patch "iwlwifi: do not use GFP_DMA in iwl_tx_queue_init" removes
GFP_DMA from allocation tx command buffers. GFP_DMA allows allocation
only for memory under 16M which causes allocation problems
suspend/resume flows.
Using kmalloc is temporal solution and some consistent/coherent
allocation schema will be more correct. Since iwlwifi hardware
supports 64bit address this solution should work on x86 (32 and
64bit) for now.

This patch is a W/A for the TSF sync issue in IBSS merging. HW is not
capable to sync TSF (it's constantly little behind). This creates
constant IBSS merging upon reception of each beacon, adding and removing
station which in turn creates above 50% packet loss and thus dramatically
degrade the throughput. The W/A simply stops the driver from declaring it
has a reliable TSF value and thus eliminates IBSS merging.

This patch addresses an issue with the locking order. ath_rx_flush_tid()
uses spin_lock/unlock_bh when IRQs are disabled in sta_notify by mac80211.
As node clean up is still pending with ath9k and this problematic portion
of the code is expected to change anyway, thinking of a proper fix may not
be worthwhile. So having this interim fix helps the users to get rid of the
kernel warning message.
Pasted the kernel warning message for reference.

When multicasting the driver sets the number of group addresses using
the count from the previous set multicast command. In general this means
you have to set the multicast addresses twice to get the behaviour you
want.
If we were multicasting, and reduce the number of addresses we are
multicasting to, then the driver would write uninitialised data from the
stack into the group addresses to multicast to.
Only write the multicast addresses we have specifically set.
