Guy Cohen 07bc28ed87 iwlwifi: more RS improvements
Main changes:
1. no need to re-calculate expected_tpt when only toggling antenna
2. changing the code to be more strict on input and status of variables
3. enhanced debug prints
4. move to search table only if improving tpt
       (don't move if SR is improved but tpt is not)

Michael Buesch f5eda47f45 b43: Rewrite LO calibration algorithm
This patch distributes the Local Oscillator calibration bursts over time,
so that calibration only happens when it's actually needed.
Currently we periodically perform a recalibration of the whole table.
The table is huge and this takes lots of time. Additionally only small bits
of the table are actually needed at a given time. So instead of maintaining
a huge table with all possible calibration values, we create dynamic calibration
settings that
a) We only calibrate when they are actually needed.
b) Are cached for some time until they expire.
So a recalibration might happen if we need a calibration setting that's not
cached, or if the active calibration setting expires.
Currently the expire timeout is set to 30 seconds. We may raise that in future.

This patch reduces overall memory consumption by nuking the
huge static calibration tables.

This patch has been tested on several 4306, 4311 and 4318 flavours.

This patch fixes several issues in security:

1) the uCode doesn't know about TKIP-MMIC failure, if uCode set
RX_RES_STATUS_BAD_ICV_MIC, it means ICV failure: drop the packet silently.
2) do not allocate room in the key table of the uCode is the set_key call
is a replacement of an old key
3) check the keyidx of the key in the uCode before removing it upon
disable_key call

Ivo van Doorn 1c01442058 mac80211: Replace ieee80211_tx_control->key_idx with ieee80211_key_conf
The hw_key_idx inside the ieee80211_key_conf structure does
not provide all the information drivers might need to perform
hardware encryption.

This is in particular true for rt2x00 who needs to know the
key algorithm and whether it is a shared or pairwise key.

By passing the ieee80211_key_conf pointer it assures us that
drivers can make full use of all information that it should know
about a particular key.

Additionally this patch updates all drivers to grab the hw_key_idx from
the ieee80211_key_conf structure.

v2: Removed bogus u16 cast
v3: Add warning about ieee80211_tx_control pointers
v4: Update warning about ieee80211_tx_control pointers

- with IWLCORE=m and/or IWL3945=m RFKILL/RFKILL_INPUT/MAC80211_LEDS/LEDS_CLASS
  are no longer wrongly forced to y
- fixes a build error with IWLCORE=y, IWL4965=m

Roland Dreier 099714934d iwlwifi: Don't unlock priv->mutex if it isn't locked
Commit b716bb91 ("iwlwifi: Cancel scanning upon association") moved the
test of priv->vif in iwl{3945,4964}_mac_config_interface() outside of
where priv->mutex is held, but still tries to do mutex_unlock() on
return.  This is clearly wrong and triggers a nasty lockdep warning when
this codepath is triggered.  Fix this by removing the mutex_unlock().

Michael Buesch 1033b3ea11 b43: Workaround DMA quirks
Some mainboards/CPUs don't allow DMA masks bigger than a certain limit.
Some VIA crap^h^h^h^hdevices have an upper limit of 0xFFFFFFFF. So in this
case a 64-bit b43 device would always fail to acquire the mask.
Implement a workaround to fallback to lower DMA mask, as we can always
also support a lower mask.

This will stop the microcode from poking with the BT GPIO line.
This fixes data transmission on this device, as the BT GPIO line

Rafael J. Wysocki b844eba292 PM: Remove destroy_suspended_device()
After 2.6.24 there was a plan to make the PM core acquire all device
semaphores during a suspend/hibernation to protect itself from
concurrent operations involving device objects.  That proved to be
too heavy-handed and we found a better way to achieve the goal, but
before it happened, we had introduced the functions
device_pm_schedule_removal() and destroy_suspended_device() to allow
drivers to "safely" destroy a suspended device and we had adapted some
drivers to use them.  Now that these functions are no longer necessary,
it seems reasonable to remove them and modify their users to use the
normal device unregistration instead.

This patch does 3 things

1) It removes the statistics work. The request statistics command is
sent in ASYNC mode in this flow, the mutex is uneeded, so the request
statistics function can't go to sleep. No need for a workqueue anymore.

2) iwl4965_send_statistics_request has been renamed to
iwl_send_statistics_request and moved to iwl-core.c

3) A request for statistics is sent in alive_notify, the makes the uCode
sends statistics notification periodically starting from association.

Michael Buesch ba380013b6 b43: Add fastpath to b43_mac_suspend()
This adds a fastpath for the common workloads to the
MAC suspend flushing.
In common workloads the FIFO flush will take between 100 and
200 microseconds. So we want to avoid calling msleep() in the
common case, as it will waste over 800 microseconds + scheduler
overhead.

This fastpath will hit in workloads where only small chunks
of data are transmitted (downloading a file) or when a TX rate bigger
or equal to 24MBit/s is used when transmitting lots of stuff (iperf).
So in the commonly used workloads it will basically always hit.

In case the fastpath is not hit, there's no real performance or latency
disadvantage from that.

And yes, I measured this. So this is not one of these
bad Programmer Likeliness Assumptions that are always wrong. ;)

Holger Schurig 8d0c7fad35 libertas: un-garbage various command structs
Some command structs contain reserved or unused fields, which the driver
send uninitialized down to the card.

Holger Schurig 7919b89c82 libertas: convert libertas driver to use an event/cmdresp queue
This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo
object for events and a swapping buffer scheme for the command response to
preserve the zero-copy semantics of the CF driver and keep memory usage low.
The main thread should only ever touch the buffer indexed by priv->resp_idx,
while the interface code is free to write to the second buffer, then swap
priv->resp_idx under the driver spinlock.  The firmware specs only permit
one in-flight command, so there will only ever be one command response to
process at a time.

Ivo van Doorn 171afcd4ba rt2x00: Only free skb when beacon_update fails
In rt2x00lib_intf_scheduled_iter() we use the hw->beacon_update()
callback function. This means that it should behave similarly as mac80211
when that uses the function.

This means that the skb should only be freed when beacon_update() has failed,
otherwise the driver is the owner and is responsible for freeing the buffer.

Stefano Brivio dc4ae1f46d b43legacy: fix DMA mapping leakage
This fixes a DMA mapping leakage in the case where we reject a DMA buffer
because of its address.
The patch by Michael Buesch has been ported to b43legacy.

Michael Buesch 4ac58469f1 ssb: Fix usage of struct device used for DMAing
This fixes DMA on architectures where DMA is nontrivial, like PPC64.
We must use the host-device's (PCI) struct device for any DMA
operation instead of the SSB device. For this we add a new
struct device pointer to the SSB device structure that will always
point to the right device for DMAing.

Without this patch b43 and b44 drivers won't work on complex-DMA
architectures, that for example need dev->archdata for DMA operations.
