ath5k only generated the beacon when bss_info_changed() was called,
but for AP mode this is not enough, because the TIM IE would never
get updated and consequently PS mode clients wouldn't know about
buffered frames. Instead, get a new beacon on every SWBA interrupt.

Under high load first data word, read after available data size
is sometimes lost in p54spi_rx. It seems to depend on frequency
of interrupts and latency of data read request relatively to
'data available' interrupt. The worst consequence of this bug
is loss of packet transmission acknowledgement, which in turn
causes overflow of tx queues and permanent link loss.
Read data size and first data word in one SPI transaction.
No packets from LMAC should have length less than 1 word,
so this shouldn't interfere with the next read transaction.
Also call p54spi_sleep if p54spi_wake succeeded.

interrupt status read
When SPI write of odd length is requested, p54spi_write splits it
into two parts: one for all data, except the last byte, and one
for last byte and padding byte. Unfortunately, the length of
first part is not amended. It works because all meaningful bytes
have proper value and the last byte of odd length SPI write
transaction is ignored.
p54spi_work has dummy HOST_INTERRUPTS register read at the end.
Drop it, as its result is not used and it has no side effects.

The previous implementation was moving back to NETWORK SLEEP state
immediately after receiving a Beacon frame. This means that we are
unlikely to receive all the buffered broadcast/multicast frames that
would be sent after DTIM Beacon frames. Fix this by parsing the Beacon
frame and remaining awake, if needed, to receive the buffered
broadcast/multicast frames. The last buffered frame will trigger the
move back into NETWORK SLEEP state.
If the last broadcast/multicast frame is not received properly (or if
the AP fails to send it), the next Beacon frame will work as a backup
trigger for returning into NETWORK SLEEP.
A new debug type, PS (debug=0x800 module parameter), is added to make
it easier to debug potential power save issues in the
future. Currently, this is only used for the Beacon frame and buffered
broadcast/multicast receiving.

We are not correctly listening to the regulatory max bandwidth
settings. To actually make use of it we need to redesign things
a bit. This patch does the work for that. We do this to so we
can obey to regulatory rules accordingly for use of HT40.
We end up dealing with HT40 by having two passes for each channel.
The first check will see if a 20 MHz channel fits into the channel's
center freq on a given frequency range. We check for a 20 MHz
banwidth channel as that is the maximum an individual channel
will use, at least for now. The first pass will go ahead and
check if the regulatory rule for that given center of frequency
allows 40 MHz bandwidths and we use this to determine whether
or not the channel supports HT40 or not. So to support HT40 you'll
need at a regulatory rule that allows you to use 40 MHz channels
but you're channel must also be enabled and support 20 MHz by itself.
The second pass is done after we do the regulatory checks over
an device's supported channel list. On each channel we'll check
if the control channel and the extension both:
o exist
o are enabled
o regulatory allows 40 MHz bandwidth on its frequency range
This work allows allows us to idependently check for HT40- and
HT40+.

Calling cancel_delayed_work() from inside
spin_lock_irqsave, introduces a potential deadlock.
As explained by Johannes Berg <johannes@sipsolutions.net>
A - lock
T - timer
phase CPU 1 CPU 2
---------------------------------------------
some place that calls
cancel_timer_sync()
(which is the | code)
lock-irq(A)
| "lock-irq"(T)
| "unlock"(T)
| wait(T)
unlock(A)
timer softirq
"lock"(T)
run(T)
"unlock"(T)
irq handler
lock(A)
unlock(A)
Now all that again, interleaved, leading to deadlock:
lock-irq(A)
"lock"(T)
run(T)
IRQ during or maybe
before run(T) --> lock(A)
"lock-irq"(T)
wait(T)
We fix this by moving the call to cancel_delayed_work() into workqueue.
There are cases where the work may not actually be queued or running
at the time we are trying to cancel it, but cancel_delayed_work() is
able to deal with this.
Also cleanup iwl_set_mode related to this call. This function
(iwl_set_mode) is only called when bringing interface up and there will
thus not be any scanning done. No need to try to cancel scanning.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13224, which was also
reported at http://marc.info/?l=linux-wireless&m=124081921903223&w=2 .

Commit e8f055f0c3b ("ath5k: Update reset code") subtly changed the
code that computes floating point values for the PHY3_TIMING register
such that the exponent is off by a decimal point, which can cause
problems with OFDM channel operation.
get_bitmask_order() actually returns the highest bit set plus one,
whereas the previous code wanted the highest bit set. Instead, use
ilog2 which is what this code is really calculating. Also check
coef_scaled to handle the (invalid) case where we need log2(0).

This removes all the dead code that tries to adjust the power
saving level based on the system AC state (inacceptable policy
in the kernel) or based on overtemp conditions (unused).
Also, pass _all_ policy wrt. enabling PS to mac80211, since
we do not use the power_disabled internally I now use that to
mirror the mac80211 CONF_PS setting. When mac80211 turns off
CONF_PS we follow suit. This means that the user power level
(which can currently only be set from sysfs) is not touched
for mac80211 powersave changes.
This means no "association status" checks are necessary since
mac80211 will not allow power save to be enabled when not
associated.

iwlwifi internally needs to keep track of whether PS
is enabled in the firmware or not. To do this, it keeps
a bit in the status flags, called STATUS_POWER_PMI.
The code to set this bit looks as follows:
static int iwl_set_power(struct iwl_priv *priv, void *cmd)
{
return iwl_send_cmd_pdu_async(priv, POWER_TABLE_CMD,
sizeof(struct iwl_powertable_cmd),
cmd, NULL);
}
int iwl_power_update_mode(...)
{
[...]
if (final_mode != IWL_POWER_MODE_CAM)
set_bit(STATUS_POWER_PMI, &priv->status);
iwl_update_power_cmd(priv, &cmd, final_mode);
cmd.keep_alive_beacons = 0;
if (final_mode == IWL_POWER_INDEX_5)
cmd.flags |= IWL_POWER_FAST_PD;
ret = iwl_set_power(priv, &cmd);
if (final_mode == IWL_POWER_MODE_CAM)
clear_bit(STATUS_POWER_PMI, &priv->status);
else
set_bit(STATUS_POWER_PMI, &priv->status);
if (priv->cfg->ops->lib->update_chain_flags && update_chains)
priv->cfg->ops->lib->update_chain_flags(priv);
[...]
}
Now, this bit really needs to track what the _firmware_
thinks, not what the driver thinks. Therefore, there is
a race condition here -- the driver sets the bit before
it knows that the async command sent to the card in the
iwl_set_power function has been processed. As a result,
the call to update_chain_flags() may think that the card
has been woken up (PMI bit cleared) while in reality it
hasn't processed the async POWER_TABLE_CMD yet.
This leads to bugs -- any commands the update_chain_flags
function sends can get stuck and subsequent commands also
fail.
The fix is almost trivial: since there's no reason to send
an async command here (in fact, there almost never should
be since many mac80211 callbacks can sleep) just make the
function wait for the card to process the command and then
return and clear the PMI bit.

This fixes a non-theoretical race condition when transmitting and
receiving frames during a scan. If the channel or operating band
changes while processing status descriptors in the tasklets, ath5k
will incorrectly use the new channel and band when reporting the
rates, even if the frame was actually sent on a previous channel.
Typically this will manifest as a beacon found on an incorrect
frequency and/or a warning in the driver while scanning:
