Johannes Berg fed732920b iwlwifi: move iwl_dump_csr to agn
The iwl_dump_csr function is only used
within the agn module, so it can be
moved there instead of being exported
by the core.

Johannes Berg a30e3112a8 iwlwifi: move agn specific station code there
By duplicating a little bit of code between 3945
and agn, we can move a lot of code into an agn
specific station management file and thus reduce
the amount of code in core that is dead to 3945.

before:
   text	   data	    bss	    dec	    hex	filename
 212886	   3872	     96	 216854	  34f16	iwlcore.ko
 620542	  10448	    304	 631294	  9a1fe	iwlagn.ko
 314013	   3264	    196	 317473	  4d821	iwl3945.ko

after:
   text	   data	    bss	    dec	    hex	filename
 202857	   3872	     92	 206821	  327e5	iwlcore.ko
 629102	  10448	    308	 639858	  9c372	iwlagn.ko
 314240	   3264	    196	 317700	  4d904	iwl3945.ko

delta:
 -10029   iwlcore.ko
   8560   iwlagn.ko
    227   iwl3945.ko

so it's a net win even if you have both loaded,
likely because a lot of EXPORT_SYMBOLs go away.

Stanislaw Gruszka 09be251e90 Revert "iwlwifi: do not perferm force reset while doing scan"
This reverts commit 7acc7c683a. It was
applied to avoid possible warning in ieee80211_restart_hw, however
reason of the warning were races in mac80211, currently hopefully fixed.

Not reseting device when performing scan is bad for two reasons.

When forcing reset from iwl_check_stuck_queue(), in case of fail,
reset will be repeated until scan finish. But since firmware is in bad
shape, scan only finish after scan_check work (about 7s). So we will
delay the reset, what is not good behaviour.

When forcing reset from iwl_recover_from_statistics(), we will not
repeat the reset, so we will not perform reset at all when needed.

Shanyu Zhao 6d6a1afdc5 iwlwifi: send DC calib config to runtime ucode
Since uCode is responsible for doing DC calibration, there's no need
to let init uCode to do initial DC calibration then send results
back to driver, then driver sends the results to runtime uCode.
Driver can simply tell runtime uCode to do DC calibration.

Actually, this patch does not disable DC calib for init uCode. It just
prevent driver from saving and sending the DC calib results (from init
ucode) to runtime uCode. The driver still uses 0xffffffff in
CALIB_CFG_CMD for init ucode.

Shanyu Zhao 6b5ce50142 iwlwifi: add iwl_nic_ops structure to iwl_ops
iwlwifi driver supports multiple devices. Since some device needs
special configuration we create a new iwl_nic_ops structure which is
configurable per device. Currently there is only one function pointer
inside this structure: additional_nic_config().

The iwl_nic_ops structure is added to the top level in struct iwl_ops,
making it easier to change per device. Duplication of the iwl_lib_ops
structure is no longer needed.

With this new ops the previous function pointer set_calib_version is
no longer needed since it is just a per device nic configuration.

As part of the code restructuring, a bug is addressed. Indication of
calib version to uCode is only needed for 6050 devices, however,
current implementation set calib version for all 6000 devices for
which DC calib is needed. To fix this, create iwl6050_ops for 6050
devices and only populate iwl_nic_ops in this structure.

Stanislaw Gruszka e7e16b90b4 iwlwifi: do not force complete scan too early
Currently we force scan complete at the end of iwl_scan_cancel_timeout
function. This cause race condition when we can get a new scan request
from mac80211 and complete it by iwl_bg_complete from older scan. Change
code to force scan complete only when really needed: device goes down,
interface is removed or scan timeout occurs.

Stanislaw Gruszka 6bd1758d97 iwlwifi: assure we complete scan in scan_abort and scan_check works
Assure we complete scan in mac80211 when we abort scanning (scan_abort
work) or scan timeout occurs (scan_check work). Currently
iwl_scan_cancel_timeout() procedure force scan finish in mac80211
at the end of timeout loop, so we can use it in proper work functions.

Stanislaw Gruszka f5354c17dc iwlwifi: force scan complete after timeout
If we do not get notification from hardware about scan complete, after
timeout do mac80211 scan completion anyway. This assure we end scan
in case of firmware hung.

Patch fix one of the causes of wdev_cleanup_work warning reported at
https://bugzilla.redhat.com/show_bug.cgi?id=593566

Stanislaw Gruszka 02d8c14b59 iwlwifi: rewrite scan completion
Assure (partially) we call ieee80211_scan_completed() only once when
scan was requested from mac80211.

Code path that first clear STATUS_SCANNING bit is responsible to call
ieee80211_scan_completed(). Before the call, we check if mac80211
really request the scan.

Still persist some cases when we behave wrong, that will be addressed
in the next patches.

Stanislaw Gruszka e693a802f0 iwlwifi: rework iwl_scan_cancel_timeout
Since on timeout version of iwl_scan_cancel procedure we can sleep,
do not have to schedule abort_scan work to begin and perform scanning,
can do this directly. Also now, as we do not queue abort_scan from
restart work anymore, we can queue abort_scan to priv->workqueue.

Don't drop mutex when waiting for scan complete. Use STATUS_HW_SCAN bit
to check if scanning is currently pending, because STATUS_SCANNING will
be cleared only with priv->mutex taken.
