[PATCH 01/28] iwlagn: add P2P NoA to probe responses

[Wey-Yi Guy]

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

Whether to use NoA or not is entire controlled
by the uCode right now, and it also adds the
attribute to beacons. We do need to add it to
probe responses in the driver though.

Keep track of the NoA notification from the
uCode and add the data to probe responses when
such are transmitted. Use RCU to manage the
lifetime.

[PATCH 02/28] iwlwifi: Suppress noisy syslog messages when RF_KILL switch engaged

[Wey-Yi Guy]

From: Todd Previte <toddX.a.previte@intel.com>

When a station is associated with an AP and the RF_KILL switch is engaged,
numerous error messages were sent to the system log. The error messages
were the result of the failure(s) of the various submodules to perform
their tasks after the radios were disabled.

To resolve this situation, the messages were modified to use a new macro,
IWL_DEBUG_QUIET_RFKILL. This macro allows for the RF_KILL error messages
to be sent to the log provided that IWL_DEBUG is true and IWL_DL_RADIO
is '1'. For all other cases, the error messages resulting from an RFKILL
event will not be sent to the system log. Messages logged because of an
RFKILL will be tagged with the prefix '(RFKILL)' to clarify the cause of
the error.

[PATCH 05/28] iwlagn: fix NULL ptr deref when reprogramming sta w/o LQ

[Wey-Yi Guy]

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

Reinette reports a crash in iwl_reprogram_ap_sta(). The
debugging shows:

  b1 16    mov    $0x16,%cl
 *f3 a5    rep movsl %ds     <-- trapping instruction:(%rsi),%es:(%rdi)

which is a memcpy of 22 (0x16) words (movsl). this points
to "priv->stations[sta_id].lq" being NULL since that is
the memcpy() of that size here.

The only way I see for this to happen is if we try to
do some RXON reprogramming while connecting to an AP,
after tx_sync() but before full setup, but that seems
like something that might very well happen.

Fix this by checking if the LQ is present and only then
reprogramming it.

[PATCH 06/28] iwlagn: use per-vif AC parameters

[Wey-Yi Guy]

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

Eliad added the ability to configure AC parameters
per virtual interface; make use of this in iwlwifi
and set the parameters in the right context. Since
storage and uploading to the device is already per
context, this is sufficient.

[PATCH 09/28] iwlagn: remove knowledge of ucode image location from upper layers

[Wey-Yi Guy]

From: Don Fry <donald.h.fry@intel.com>

The upper layers of the driver do not need to know where the ucode is
stored.  It already passes in an enum of which ucode to load.  Let the
lower layer routines select the ucode to load.

[PATCH 10/28] iwlagn: push knowledge of ucode image lower down

[Wey-Yi Guy]

From: Don Fry <donald.h.fry@intel.com>

Move the knowledge of the ucode image to lower level routines.  Also do
not pass the iwl_priv structure lower than it needs to be.

[PATCH 12/28] iwlwifi: move all mac80211 related functions to one place

[Wey-Yi Guy]

There are many mac80211 callback functions in the driver, as current
implementation, those functions are scatter everywhere which is very difficult
to find and maintain, move all the mac80211 callback functions into single
file. There should be no functional changes

[PATCH 13/28] iwlagn: explicitly program P2P QoS parameters

[Wey-Yi Guy]

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

In P2P device mode, the device needs to have valid
QoS parameters. We currently have those because we
program parameters from any virtual interface into
all contexts, but not only do we want to get rid of
this -- it is also unpredictable since on the BSS
context we might have any parameters, and there it
might even be programmed for HT.

Explicitly program default QoS parameters into the
PAN context for P2P (the defaults are 11g but with
QoS disabled) to make device behaviour predictable.

This also helps when in a follow-up patch we will
use TX QoS parameters from mac80211 only for the
context they were meant for -- without this first
that would completely break P2P device discovery.

[PATCH 17/28] iwlwifi: Move the core suspend function to iwl-agn-lib

[Wey-Yi Guy]

The core suspend function is part of agn, iwl_mac80211 should only
handle mac80211 I/F operations.

[PATCH 22/28] iwlagn: don't always split remain-on-channel

[Wey-Yi Guy]

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

Due to the P2P context always having the associated
bit set when we got to this code, we were splitting
up the remain-on-channel durations unconditionally.
This isn't needed -- if the P2P context is in P2P
device type mode it doesn't impose restrictions on
timing to skip it in that case.

[PATCH 26/28] iwlwifi: fix rate-scaling algorithm for BT combo devices

[Wey-Yi Guy]

From: Venkataraman, Meenakshi <meenakshi.venkataraman@intel.com>

iwlwifi tries to avoid using antenna B in BT combo devices when BT
is active. A bug in the rate-scaling algorithm was causing the combo
device to never attempt MIMO rates. Fix the algorithm to
opportunistically try MIMO rates when BT traffic is low.

[PATCH 27/28] iwlagn: Remove dependence of iwl_priv from eeprom routines.

Make the eeprom routines less dependent on the iwl_priv structure.
Don't use the priv when bus structure is sufficient.

[PATCH 28/28] iwlagn: move nvm_device_type from iwl_priv to iwl_trans

[Wey-Yi Guy]

From: Don Fry <donald.h.fry@intel.com>

The nvm_device_type is eeprom related and does not need to be part
of the iwl_priv structure.  Move it and eliminate access to the iwl_priv
structure.

Patch 25 should have been merged into this one :)

This breaks P2P and patch 13 fixes it again, can't we get those in the
right order?
