      iwlagn: move IO functions out of line · 02a7fa00
      Johannes Berg authored 
      This generates a massive reduction in module size:
with debug:
   text	   data	    bss	    dec	    hex	filename
 670300	  13136	    420	 683856	  a6f50	iwlagn.ko (before)
 388347	  13136	    408	 401891	  621e3	iwlagn.ko (after)

without debug:
   text	   data	    bss	    dec	    hex	filename
 528575	  13072	    420	 542067	  84573	iwlagn.ko (before)
 294192	  13072	    408	 307672	  4b1d8	iwlagn.ko (after)

This also removes all the IO debug functionality since
it can easily be replaced by tracing, and makes the
code unnecessarily complex.

I haven't done any CPU utilisation measurements, but
given that the hotpaths don't use much IO it is not
likely to have a negative impact; in fact, the size
reduction will reduce cache pressure which possibly
improves performance.

Finally, an unused function or two were removed.

      iwlwifi: move agn specific station code there · a30e3112
      Johannes Berg authored 
      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.

      iwlwifi: LED cleanup · e932a609
      Johannes Berg authored 
      The iwlwifi drivers have LED blinking requirements that
mac80211 cannot fulfill due to the use of just a single
LED instead of different ones for TX, RX, radio etc.
Instead, the single LED blinks according to transfers
and is solid on the rest of the time. As such, having
LED class devices registered that mac80211 triggers are
connected to is pointless as we don't use the triggers
anyway.

Remove all the useless code and add hooks into the
driver itself. At the same time, make the LED code
abstracted so the core code that determines blink rate
etc. can be shared between 3945 and agn in iwlcore.

At the same time, the fact that we removed the use of
the mac80211 LED triggers means we can also remove the
IWLWIFI_LEDS Kconfig symbol since the LED support is
now self-contained.

      iwlwifi: device tracing · be1a71a1
      Johannes Berg authored 
      In order to have an easier way to debug issues, create
trace events (using the ftrace framework) that will
allow us to follow exactly what the driver is doing
with the device.

The text format isn't all that useful, but the binary
format can also be obtained easily via debugfs and
then analysed on the fly or offline with debugging
tools.

      iwlwifi: Fix and rework Kconfig file · 80bc5393
      Reinette Chatre authored 
      Fixes:
- iwlwifi is an optional driver and should thus not default to 'y'.
- 3945 now depends on IWLCORE.

Rework:
- There is not a case when IWLCORE should not be selected. At the same time
  the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of
  these two. With IWLWIFI being the driver name we proceed to use just it and
  replace instances of IWLCORE with it. The module name does not change
  and is still iwlcore.
- Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move
  this up to one select when IWLWIFI is selected.
- IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series.
- Now that 3945 depends on IWLWIFI we can also indicate its dependency on
  MAC80211_LEDS and LEDS_CLASS at this level.
- IWLAGN_LEDS is not used by driver - remove it.
- IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part
  of iwlcore module. Move this config up in Kconfig to reflect that and also
  change name to IWLWIFI_SPECTRUM_MEASUREMENT.
- CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to
  description that indicates this.
- CONFIG_IWL3945_RFKILL does not exist - remove usage from driver.
- Add "iwlagn" to end of description of IWLAGN to help people understand
  what iwlagn means in rest of Kconfig text.
- Add "iwl3945" to end of description of IWL3945 to help people understand
  what iwlagn means in rest of Kconfig text.
- Change IWLWIFI_DEBUGFS description to indicate that only iwlagn supports
  it (for now).
