Hi John,

This pull request is intended for 3.16.

The regular amount of housekeeping here. I merged iwlwifi-fixes.git to be able to add the patch you didn't want in wireless.git at that stage of the -rc cycle.
Luca has a few preparations for CSA implementation and also what seems to be a bugfix for P2P but hasn't caused issues we could notice.

Please pull.

[PATCH 01/11] iwlwifi: mvm: update power after phy_ctxt is NULL when unassigning chanctx

[Emmanuel Grumbach]

From: Luciano Coelho <luciano.coelho@intel.com>

iwl_mvm_power_update_mac() (more specifically
iwl_mvm_power_iterator()) relies on the phy_ctxt setting to decide
whether the vif is active or not.  When unassigning a chanctx, we
should therefore call iwl_mvm_power_update_mac() after setting
phy_chanctx to NULL.

We should not allow diversity when BT Coex needs the second
antenna. Thermal Throttling can also request to stop using
the second antenna. Honour those requests.

[PATCH 04/11] iwlwifi: mvm: enable MAC_FILTER_IN_BEACON when forced_assoc_off is set

From: Luciano Coelho <luciano.coelho@intel.com>

Set the MAC_FILTER_IN_BEACON flag in iwl_mvm_mac_ctxt_cmd_sata() also
when forced_assoc_off is set, so it's aligned with when we are not
associated.

[PATCH 05/11] iwlwifi: mvm: set the MAC_FILTER_IN_BEACON flag also for P2P

[Emmanuel Grumbach]

From: Luciano Coelho <luciano.coelho@intel.com>

There doesn't seem to be a good reason for not enabling the
MAC_FILTER_IN_BEACON flag for P2P client, as we do for station.

This can prevent potential, hard-to-reproduce problems during
association.

[PATCH 06/11] iwlwifi: mvm: don't filter out the first beacon

[Emmanuel Grumbach]

From: Avri Altman <avri.altman@intel.com>

Enabling beacon filtering should be done only after a beacon
has been received. Doing that too early will cause
disconnections.
This has already been fixed, but the fix didn't take care
about the case where the beacon is received after the
association, it waited only for association which is not
enough.

[PATCH 07/11] iwlwifi: mvm: pass force_assoc_off all the way down to avoid hacks

[Emmanuel Grumbach]

From: Luciano Coelho <luciano.coelho@intel.com>

In some cases, we need to force the association to be off in the
MAC_CONTEXT_CMD command we send to the firmware.  Instead of having to
hack the vif->bss_conf.assoc value, pass it all the way down the call
chain.

Additionally, for the iwl_mvm_mac_ctxt_add() case, we *always* set
forced_assoc_off to true, so we can remove the hack in the d3 code
that was forcing it to off by hacking the bss_conf.assoc value.

[PATCH 11/11] iwlwifi: mvm: remove vif argument from power_update_mac

[Emmanuel Grumbach]

From: Arik Nemtsov <arik@wizery.com>

The power update function looks at all current vifs to determine the power
policy. It doesn't use the current vif. Instead the value was overwritten
and used internally.
