[PATCH 01/13] iwlagn: reserve queue 10 for TX during scan dwell

[Wey-Yi Guy]

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

New uCode images will use queue 10 for TX
during scan (for P2P offchannel operation
scan). We'll bump the API version of those,
but before we need to reserve queue 10 and
stop using it for aggregation.

To simplify the code, always reserve it,
we could continue using it on older uCode
images but that'd be rather complicated.
Also, we'll set it up to map to the right
FIFO as needed later, but as we don't use
the queue now that doesn't hurt.

[PATCH 05/13] iwlagn: separate firmware version warning

[Wey-Yi Guy]

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

We sometimes need to support new firmware API for
a while before we can publish them since testing
them fully takes a long time. We could keep all
the new code private, but that causes plenty of
problems and sometimes we can give a pre-release
version of firmware to people who need to test.
However, when we just bump the API version, the
driver will warn everybody that their firmware is
outdated, when in fact it isn't. (Currently our
case for this doesn't really change the API but
bumping the API version is necessary because the
firmware isn't fully backward compatible)

In order to handle this in the future, add a new
"api_ok" version; only below this will the driver
warn that the uCode is too old.

[PATCH 06/13] iwlagn: bump firmware API for some devices

[Wey-Yi Guy]

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

We're working on improvements for the firmware
for some devices, and need to bump the API for
those since they won't be backward compatible
completely (the earlier patch reserving queue
10 for P2P).

Bump the API version to 6 for those devices
but don't warn users of version 5 yet.

[PATCH 07/13] iwlagn: move context init after firmware loading

[Wey-Yi Guy]

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

The availability of contexts depends on the
firmware capabilities. Currently only the
presence of the second context depends on it,
but soon P2P support will also be different.
Move the context initialisation code to the
firmware-dependent setup before registering
with mac80211 to make it easier to handle.

[PATCH 08/13] iwlagn: support new P2P implementation

[Wey-Yi Guy]

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

The previous P2P implementation turned out to
not work well and new uCode capabilities were
added to support P2P. Modify the driver to
take advantage of those, and also discover P2P
support automatically based on a uCode flag
instead of having a Kconfig symbol for P2P.

[PATCH 09/13] mac80211: remove offchannel_tx API

[Wey-Yi Guy]

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

For iwlwifi, I decided not to use this API since
it just increased the complexity for little gain.
Since nobody else intends to use it, let's kill
it again. If anybody later needs to have it, we
can always revive it then.

[PATCH 13/13] iwlagn: handle GO powersave

[Wey-Yi Guy]

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

In order to implement support for GO powersave on
the P2P client side, the ucode needs to know what
GO we're trying to authenticate/associate with,
it needs to have a station entry and the BSSID in
the RXON set.

Implement the new mac80211 callbacks to give this
data to the device.

Since this is also useful for the device when a
normal connection is established, also program it
with the information in that case.

Re: [PATCH 00/11] update for 3.2

[Guy, Wey-Yi]

Hi John,

Please ignore this patch set, I don't mean to send it.
The only patch I need to send is the "handle GO powersave" path.

I will send the single patch separated.

Sorry for the mistake.

Wey
