[PATCH 0/15] update for 3.3: iwlwifi 2011-12-08

[Wey-Yi Guy]

We disable P2P by default, P2P feature still under development and it is 
not 100% stable yet. If anyone interest and want to use it, it is always
can be enable through .config
We also include number of enhancements for testmode operation, the testmode
will be used by iwlwifi for validation and debugging
Also more works for the driver partition being added here.

Don Fry (3):
  iwlwifi: move eeprom pointer from iwl_priv to iwl_shared
  iwlwifi: move device_pointers from iwl_priv to iwl_shared
  iwlwifi: move calib_results list from iwl_priv to iwl_trans

Hsu, Kenny (3):
  iwlwifi: add uCode version information support by testmode
  iwlwifi: hide kernel option IWLWIFI_DEVICE_SVTOOL
  iwlwifi: add device ID information support by testmode

Johannes Berg (3):
  iwlagn: fix TID use bug
  iwlagn: use IWL_MAX_TID_COUNT for WoWLAN
  iwlagn: use IWL_MAX_TID_COUNT instead of TID_MAX_LOAD_COUNT

Wey-Yi Guy (6):
  iwlwifi: Display more uCode debug info
  iwlwifi: minor cleanup
  iwlwifi: remove reference to legacy devices
  iwlwifi: rename CONFIG_IWLWIFI_DEVICE_SVTOOL to
    CONFIG_IWLWIFI_DEVICE_TESTMODE
  iwlwifi: P2P is not enabled by default
  iwlwifi: set TX_CMD_FLG_STA_RATE_MSK for BAR frame

Why not use wiphy.fw_version which is specifally meant for this purpose?

fw_version is being formatted to string. we need u32

If the u32 format is so important (and I suspect it isn't, most likely
you have string format for your version numbers as well) you can always
format the u32 to hex, for example "0xdeadbeef".

Sure, it's ugly but still less ugly than having a private interface in
the driver. The idea of nl80211 testmode is NOT to replicate wext
private interface.

it is ugly :-)
We are not try to replicate wext private interface, but just try to
support the need for our existing debugging applications.

Doing so will mean change the existing OS agnostic applications to
understand "string" format.

[PATCH 02/15] iwlwifi: hide kernel option IWLWIFI_DEVICE_SVTOOL

[Wey-Yi Guy]

From: Hsu, Kenny <kenny.hsu@intel.com>

Because the testmode support should be the mandatory foundation
of test functionality, it is better to set kernel option
IWLWIFI_DEVICE_SVTOOL automatically instead of user configuration.

+       bool "iwlwifi experimental P2P support"
+       depends on IWLWIFI
+       help
+         This option enables experimental P2P support for some devices
+         based on microcode support. Since P2P support is still under
+         development, this option may even enable it for some devices
+         now that turn out to not support it in the future due to
+         microcode restrictions.
+
+         To determine if your microcode supports the experimental P2P
+         offered by this option, check if the driver advertises AP
+         support when it is loaded.
+
+         Say Y only if you want to experiment with P2P.

[PATCH 13/15] iwlagn: fix TID use bug

[Wey-Yi Guy]

From: Johannes Berg <johannes.berg@intel.com>

The driver everywhere uses max TID count as 9,
which is wrong, it should be 8.

I think the reason it uses 9 here is off-by-one
confusion by whoever wrote this. We do use the
value IWL_MAX_TID_COUNT for "not QoS/no TID"
but that is completely correct even if it is 8
and not 9 since 0-7 are only valid.

As a side effect, this fixes the following bug:

 Open BA session requested for 00:23:cd:16:8a:7e tid 8
 ------------[ cut here ]------------
 kernel BUG at drivers/net/wireless/iwlwifi/iwl-trans-pcie-int.h:350!
 ...

when you do
echo "tx start 8" > /sys/kernel/debug/ieee80211/*/*/*/*/agg_status

[PATCH 14/15] iwlagn: use IWL_MAX_TID_COUNT for WoWLAN

[Wey-Yi Guy]

From: Johannes Berg <johannes.berg@intel.com>

Now that I corrected IWL_MAX_TID_COUNT to be 8
instead of 9, we can use it in WoWLAN suspend.

[PATCH 15/15] iwlagn: use IWL_MAX_TID_COUNT instead of TID_MAX_LOAD_COUNT

[Wey-Yi Guy]

From: Johannes Berg <johannes.berg@intel.com>

We track the load only on 8 TIDs, previously this
was TID_MAX_LOAD_COUNT. Since IWL_MAX_TID_COUNT
is now 8 as well, use that to make the code more
easily understandable.
