Following the tradition we have had with ath5k, ath9k, CRDA,
wireless-regdb I'd like to license this code under the permissive ISC
license for the code sharing purposes with other OSes, it'd sure be nice
to help the landscape in this area. Although I am %82.89 owner of the
regulatory code I have asked every contributor to the regulatory code
and have receieved positive Acked-bys from everyone except two deceased
entities:

 o Frans Pop RIP 2010 [0]
	- Frans Pop <elendil@planet.nl>
	- Frans Pop <fjp@debian.org>
 o Nokia     RIP February, 11, 2011 [1], [2]
	- ext-yuri.ershov@nokia.com
	- kalle.valo@nokia.com

Frans Pop's contribution was a simple patch 55f98938, titled,
"wireless: remove trailing space in messages" which just add a \n
to some printk lines. I'm going to treat these additions as
uncopyrightable.

As for the contributions made by employees on behalf of Nokia
my contact point was Petri Karhula <petri.karhula@nokia.com> but
after one month he noted he had not been able to get traction from the
legal department on this request, as such it I proceeded by replacing
their contributions in previous patches.

The end goal is to help a clean rewrite that starts in userspace
that is shared under ISC license which currently is taking place with
the regulatory simulator [3].

    cfg80211: indent regulatory messages with spaces

    The regulatory messages in syslog look weird:

    kernel: cfg80211: Regulatory domain: US
    kernel: ^I(start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
    kernel: ^I(2402000 KHz - 2472000 KHz @ 40000 KHz), (600 mBi, 2700 mBm)

    kernel: ^I(5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 3000 mBm)

    Indent them with four spaces instead of the tab character to get prettier
    output.

When cancelling a delayed work (timer) in L2CAP we can not sleep holding
the sock mutex otherwise we might deadlock with an L2CAP timer handler.
This is possible because RX/TX and L2CAP timers run in different workqueues.
The scenario below illustrates the problem. Thus we are now avoiding to
sleep on the timers locks.

When mac80211 relays a frame from STA1 to STA2 in AP mode it will get
re-classified in the tx path. Unfortunately the frame protocol field
is always set to ETH_P_8023 while the classification only kicks in
for ETH_P_IP. Hence, a high priority frame from STA1 will be send to
STA2 as best effort.

Instead of running classification on the frame just use the same
priority as STA1 did. Do this by adding 256 to the skb->priority
to allow cfg80211_classify8021d to shortcut frame classification.

Currently due to following issues in the code even if device is
configured in B only, G only or BG mode using iw bitrates command,
ibss is getting created in BGN mode.

1) mwifiex_channels_to_cfg80211_channel_type() routine gives channel
type as NL80211_CHAN_HT20 for non-HT channel as well, because driver
doesn't store HT information provided by stack for the channel.
This issue is fixed by maintaining channel type information in
'adapter->channel_type'.
2) Band configuration is unnecessarily overwritten with BGN/AN while
setting channel.

This patch makes sure that "adapter->config_bands" correctly gets
modified while setting channel.

Replace driver specific macros with the corresponding
IEEE80211_HT_PARAM_CHA_SEC_* macros defined in ieee80211.h.
Also, rename 'adapter->chan_offset' to 'adapter->sec_chan_offset'
for consistency.

struct mwifiex_ds_band_cfg and mwifiex_set_radio_band_cfg() routine
are unnecessary. It can be done with simple equivalant code.

The IBSS merge code calls ieee80211_sta_expire() with a relatively
short expire timeout that purges other clients prematurely. The
expire function has to check that only the clients belonging to
the vif in question are purged.

When stack calls ampdu_action with action = IEEE80211_AMPDU_TX_STOP
for a stream that has already been removed from the driver, call
ieee80211_tx_ba_stop_irqsafe to clear the stream in the stack.

Joe changed ath_dbg() to simpify code but while his patch was
being merged dfs.c was born and as such did not get the change
Joe envisioned. This fixes that. Test compiled with:

 make allmodconfig

The ICT code erroneously uses PAGE_SIZE. The bug
is that PAGE_SIZE isn't necessarily 4096, so on
such platforms this code will not work correctly
as we'll try to attempt to read an index in the
table that the device never wrote, it always has
4096-byte pages.

Additionally, the manual alignment code here is
unnecessary -- Documentation/DMA-API-HOWTO.txt
states:
  The cpu return address and the DMA bus master address are both
  guaranteed to be aligned to the smallest PAGE_SIZE order which
  is greater than or equal to the requested size.  This invariant
  exists (for example) to guarantee that if you allocate a chunk
  which is smaller than or equal to 64 kilobytes, the extent of the
  buffer you receive will not cross a 64K boundary.

Just use appropriate new constants and get rid of
the alignment code.
