Hi John,

This is a pull request intended for 3.17. Note that I merged wireless-next because of dependencies on mac80211.
I also merged iwlwifi-fixes to avoid conflicts.

Highlight here is the continuation of CSA by Andrei and Luca and Arik's work on TDLS - both are yet to be continued.
David has a new firmware API for Scan, and I add a new API for BT Coex. Along with that, the usual amount of work on new devices and fixes.

Please pull. Thanks!

[PATCH 03/40] iwlwifi: mvm: don't collect logs in the interrupt thread

[Emmanuel Grumbach]

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Instead of reading all the data in the context of the
interrupt thread, collect the data in the restart flow
before the actual restart takes place so that the device
still has all the information.
Remove iwl_mvm_fw_error_sram_dump and move its content to
iwl_mvm_fw_error_dump.

[PATCH 07/40] iwlwifi: mvm: read the mac address in family 8000

[Emmanuel Grumbach]

From: Eran Harary <eran.harary@intel.com>

In family 8000 products the MAC address in the OTP could be in either:
- WFPM address
- PCIE address
In sdio product we should read it from the WFPM, in pcie product we
should read it from the PCIe location.
This is relevant only from otp version 0xE08 and above.
While at it, fix the bytes order in version 0xE08.

[PATCH 10/40] iwlwifi: mvm: BT Coex - prepare towards new API

[Emmanuel Grumbach]

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

A new API is coming. This new API is not backward
compatible. So we need to keep the old commands to be able
to work with the former API.
Move all the current code into a new file: coex_legacy.
If a firmware with the new API is detected, we currently
just bail out since the implementation of the new API will
come in future patches.

Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

[PATCH 11/40] iwlwifi: mvm: BT Coex - new API

[Emmanuel Grumbach]

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Start the new BT Coex implementation.
Don't react to notifications for now - only the initial
configuration is implemented. The rest will happen in next
patches.
Since coex.c now uses the new the new structures in all
functions, we need to adapt the code to compile, even if it
doesn't run yet.

[PATCH 12/40] iwlwifi: mvm: BT Coex - convert the sw boost update to new API

[Emmanuel Grumbach]

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

No need to send the big BT_COEX_CMD command, we have now
a much thiner command that updates only what is needed.
Adapt the code to that, and open the patch to the updates.

Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

[PATCH 13/40] iwlwifi: mvm: BT Coex - convert the co-running update to new API

[Emmanuel Grumbach]

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

No need to send the big BT_COEX_CMD command, we have now
a much thiner command that updates only what is needed.
Adapt the code to that.

[PATCH 18/40] iwlwifi: mvm: rs: don't clear persistent fields

[Emmanuel Grumbach]

From: Eliad Peller <eliad@wizery.com>

iwl_mvm_rs_rate_init() is called multiple times to re-init
the rate scaling statistics (e.g. after some idle time).

It clears all the lq_sta sta, including some fields that
shouldn't be cleared (e.g. debugfs pointers). Fix it
by adding a new 'persistent' sub-struct, and
avoid clearing it on (re-)init.

Move the initialization of the persistent fields to
rs_alloc_sta instead.

[PATCH 24/40] iwlwifi: mvm: let iwl_mvm_update_quotas disregard a disabled vif

[Emmanuel Grumbach]

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

In some cases (e.g. when we're doing a channel switch), we may need to
disable the quota of a vif temporarily.  In order to do so, add an
argument to the iwl_mvm_update_quotas() function to tell if the passed
vif is a new one or if it should be disregarded.

[PATCH 25/40] iwlwifi: mvm: don't send zero quota to the firmware

[Emmanuel Grumbach]

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

There are some cases where we can currently send zero quota
for a valid binding, e.g. if we update while an interface is
bound to a channel context but not yet acting as an AP.

Avoid this by reordering the checks.

[Emmanuel Grumbach]

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

The firmware currently deals with zero quota for a given
binding, but it seems odd to send that down. Make sure
that we don't do that.

[PATCH 27/40] iwlwifi: mvm: don't pass update type to quota iterator

[Emmanuel Grumbach]

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

Simplify the quota iterator by not passing the update type,
it only needs to know whether or not to skip an interface.

[PATCH 28/40] iwlwifi: mvm: remove update type argument from quota update

[Emmanuel Grumbach]

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

It turns out that adding the update type argument was pointless as
quota update is never called from the add_interface() callback.
Therefore, IWL_MVM_QUOTA_UPDATE_TYPE_NEW isn't actually needed and
then only a "disabled_vif" argument is needed for the upcoming CSA
work.

Remove the whole enum iwl_mvm_quota_update_type and pass the right
arguments (always NULL for disabled vif right now) to the function
in all current call sites.

[PATCH 29/40] iwlwifi: mvm: add switch_vif_chanctx operation

[Emmanuel Grumbach]

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

Implement the switch_vif_chanctx operation with support for a
single-vif and SWAP mode.  The REASSIGN mode and multi-vifs are not
supported yet.

This operation needs to implement 4 steps, namely unassign, remove,
add and assign the chanctx.  In order to do this, split out these
operations into locked and non-locked parts, thus allowing us to call
them while locked.

Additionally, in order to allow us to restart the hardware when
something fails, add a boolean to the iwl_mvm_nic_restart() function
that tells whether the restart was triggered by a FW error or
something else.

[PATCH 30/40] iwlwifi: mvm: CSA unbind-bind flow support for client

[Emmanuel Grumbach]

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

Implement support for unbind-bind flow for the client roles.  This
includes telling the firmware that we are not associated, removing
time-events, removing quotas and updating power management during the
actual switch, and redoing everything in the new channel.

[PATCH 33/40] iwlwifi: mvm: Reflect GO channel switch in NoA

[Emmanuel Grumbach]

From: Andrei Otcheretianski <andrei.otcheretianski@intel.com>

According to the spec, GO/AP should perform the channel switch just
before "beacon 0". However, since the exact timing isn't defined,
it may result in a sudden GO disappearance from the channel.
Prevent potential packet loss when performing the CS by scheduling
NoA time event and executing the channel switch flow when a notification

[PATCH 34/40] iwlwifi: mvm: Use CS tx block bit for AP/GO

[Emmanuel Grumbach]

From: Andrei Otcheretianski <andrei.otcheretianski@intel.com>

An AP/GO may perform the channel switch slightly before its stations.
This scenario may result in packet loss, since the transmission may start
before the client is actually on a new channel. In order to prevent
potential packet loss disable tx to all the stations when the channel
switch flow starts. Clear the disable_tx bit when a station is seen on a
target channel, or after IWL_MVM_CS_UNBLOCK_TX_TIMEOUT beacons on a new
channel. In addition call ieee80211_sta_block_awake in order to inform
mac80211 that the frames for this station should be buffered.

[PATCH 35/40] iwlwifi: mvm: disallow new TDLS stations when appropriate

[Emmanuel Grumbach]

From: Arik Nemtsov <arik@wizery.com>

HW/FW constraints dictate that TDLS should only be used when a single
phy ctx is active. We also support at most 4 TDLS peers. We don't
support TDLS on a P2P vif.

Unify and move a phy-ctx counting implementation from the power-mgmt code
in order to simplify implementation.

[PATCH 39/40] iwlwifi: mvm: remove 8000 HW family setting of adc sampling on nic config

[Emmanuel Grumbach]

From: Liad Kaufman <liad.kaufman@intel.com>

This patch removes the setting of the ADC sampling bits in
the mvm nic configuration. This setting is not required by
the firmware, and furthermore - it interferes with the DBGC
when it is running in DRAM mode on PCIe.

[PATCH 40/40] iwlwifi: mvm: minor fix in comment

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

The comment was not accurate, we are talking about the frames
*for* the station and not from the station.
