Emmanuel Grumbach f0832f137c iwlwifi: HW dependent run time calibration
This patch does several things:

1) rename CONFIG_IWL4965_SENSITIVITY to IWL4965_RUN_TIME_CALIB which is
   better semantic
2) move all the run time calibration to a new file: iwl-calib.c
3) simplify the sensitivity calibration flow and make it HW dependent
4) make the chain noise calibration flow HW dependent

Adrian Bunk 1da5ea1a8b iwlwifi: make IWLWIFI a tristate
IWLWIFI should be a tristate so that if IWLCORE and/or IWL3945 are m
and none of them is y kbuild doesn't create an empty 
drivers/net/wireless/built-in.o

This patch also removes the pointless "default n".

Bill Moss 786b455707 iwlwifi: fix debug messages during scanning
direct_mask will be set when we are not associated and requesting a
direct scan. The second debug print will be confusing as priv->essid
is not set at that time and it will thus print "<hidden>" while it is
known to which AP a direct scan is requested - as previous debug message
also indicates.

Now make all debugging consistent.

Adrian Bunk 3a8209d19d iwlwifi: move the selects to the tristate drivers
This patch moves the following select's:
- RFKILL        : IWLWIFI_RFKILL -> IWLCORE
- RFKILL_INPUT  : IWLWIFI_RFKILL -> IWLCORE
- MAC80211_LEDS : IWL4965_LEDS   -> IWLCORE
- LEDS_CLASS    : IWL4965_LEDS   -> IWLCORE
- MAC80211_LEDS : IWL3945_LEDS   -> IWL3945
- LEDS_CLASS    : IWL3945_LEDS   -> IWL3945

The effects are:
- 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
  might be a bug in kconfig causing it, but doing this change that is 
  anyway the right thing fixes it

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

this codepath is triggered.  Fix this by removing the mutex_unlock().

Emmanuel Grumbach 49ea85961c iwlwifi: remove the statistics work
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.

When driver is notified of association the upper layer will be notified
right after that the association is complete. Doing the post association

Mohamed Abbas ab53d8af67 iwlwifi: Add led support
This patch add LEDS support to 3965 and 4965 drivers. It is based on
led trigger and class. For our drivers we needed to avoid two things.
1- We receive led trigger on/off on each Rx\Tx frame. In our driver
    we can not call led command like that. In this driver once driver
    receive a start of traffic it call the led command to start blinking
    then we count all bytes of Tx and Rx frame, after two second we count the
    blink rate of last two second then id blink rate changed we call the led
     commands
2- Since we can call led command very often, we make sure we call the
    led command after we receive the statistics notification so
    we don't need to wake up the ucode id it is in sleep state.
    This patch was tested with 4965 and 3945.

units rather than 0.1msec units. 0.1msec units are only required
by atheros hardware (according to current driver support), all

Therefore, it results in fewer calculations and more precision

Johannes Berg 8318d78a44 cfg80211 API for channels/bitrates, mac80211 and driver conversion
This patch creates new cfg80211 wiphy API for channel and bitrate
registration and converts mac80211 and drivers to the new API. The
old mac80211 API is completely ripped out. All drivers (except ath5k)
are updated to the new API, in many cases I expect that optimisations
can be done.

Along with the regulatory code I've also ripped out the
IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be
unnecessary if the hardware simply gives us whatever channels it wants
to support and we then enable/disable them as required, which is pretty
much required for travelling.

Additionally, the patch adds proper "basic" rate handling for STA
mode interface, AP mode interface will have to have new API added
to allow userspace to set the basic rate set, currently it'll be
empty... However, the basic rate handling will need to be moved to
the BSS conf stuff.

I do expect there to be bugs in this, especially wrt. transmit
power handling where I'm basically clueless about how it should work.

- requests by mac80211 to low-level driver to start/stop Tx aggregation.

- async feedback by low-level to mac80211 to inform that HW is ready for

Cyrill Gorcunov 18904f5839 wireless: iwlwifi3945/4965 - fix incorrect counting of memory
This patch does fix incorrect counting of memory allocated by kmalloc.
It seems that could lead to allocated memory overrun and corrupt
nearlaid memory area.

Eric Sandeen 9e7d1a445e iwlwifi: correct math in elapsed_jiffies
w/o the first change: if end == start you get MAX_JIFFY_OFFSET which
isn't what you want...

For the latter I think to be technically correct you need the +1 to
account for the jiffy between MAX_JIFFY_OFFSET and 0

(hmm w/ the 2nd change the first isn't strictly needed... ah well)

Gregory Greenman 76f3915b4c iwlwifi: Fix uCode error on association
The problem is that priv->assoc_id is set when assoc. resp frame is
received. But, when it is set, LQ cmd is still not sent to the uCode, it is
done from bg_post_assoc, which is called through a workqueue.

On the other hand, when a tx arrives at the moment when this flag is set,
but LQ is still not sent, the if condition in tx_skb will not hold and
the frame will not be dropped.  Thus, it will be sent through
which is still not in the sta table in the uCoded.

Joonwoo Park 25c03d8e8c iwlwifi: do not schedule tasklet when rcv unused irq
The nic controller's scheduler interrupt (CSR_INT_BIT_SCD) indicates
to the driver that scheduler finished to transmit the frame/frames.
This bit is not used and the tasklet should thus not be scheduled upon
its receipt.

Reinette Chatre 74a3a2509d iwlwifi: cleanup usage of inline functions
Be consistent when using inline functions. If the function only used
once we move it to where it is used - no need for externs.

Reinette Chatre 849e0dcea6 iwlwifi: initialize geo/channel information during probe
The geo/channel information is obtained from the EEPROM, which is read
during probe. We can thus set up channel information at this time. This
helps us to support ioctl commands that rely on this before the interface
is brought up.

Clearly matches _init_channel_map with _free_channel_map and _init_geos
with _free_geos to ensure functions calling these routines can also call
their cleanup routines.

Fixes a few bugs:
- if channel information is not available when ioctl commands are
  issued then we get a NULL pointer oops. Having channel information
  set up during probe we can deal with ioctl commands without requiring
  interface to be brought up.
  This fixes bug: http://www.bughost.org/bugzilla/show_bug.cgi?id=1552
- Fix potential problem if user triggers probe/remove/probe sequence. The
  value of priv->channel_count was used to determine if channel map is
  set up. This value was never reset when channel map was removed.
- Fix memory leak: priv->modes need to be freed when device removed.
