154b0296c0 wifi: nl80211: Add a notification to notify NAN channel evacuation 
If all available channel resources are used for NAN channels, and one of
them is shared with another interface, and that interface needs to move
to a different channel (for example STA interface that needs to do a
channel or a link switch), then the driver can evacuate one of the NAN
channels (i.e. detach it from its channel resource and announce to the
peers that this channel is ULWed). In that case, the driver needs to
notify user space about the channel evacuation, so the user space can
adjust the local schedule accordingly.

Add a notification to let userspace know about it.

f826534483 wifi: nl80211: allow reporting spurious NAN Data frames 
Currently we have this ability for AP and GO. But it is now needed also for
NAN_DATA mode - as per Wi-Fi Aware (TM) 4.0 specification 6.2.5:
"If a NAN Device receives a unicast NAN Data frame destined for it, but
 with A1 address and A2 address that are not assigned to the NDP, it shall
 discard the frame, and should send a Data Path Termination NAF to the
 frame transmitter"

To allow this, change NL80211_CMD_UNEXPECTED_FRAME to support also
NAN_DATA, so drivers can report such cases and the user space can act
accordingly.

c4aa273ff6 wifi: nl80211: define an API for configuring the NAN peer's schedule 
Add an NL80211 command to configure the NAN schedule of a NAN peer.
Such a schedule contains a list of NAN channels, and a mapping from each
time slots to the corresponding channel (or unscheduled).
Also contains more information about the schedule, such as sequence ID
and map ID.

Not all of the restrictions are validated in this patch. In particular,
comparison of two maps of the same peer requires storing/retrieving each
map of each peer, only for validation.
Therefore, it is the responsibilty of the driver to check that.

1f1101c29e wifi: nl80211: add support for NAN stations 
There are 2 types of logical links with a NAN peer:
- management (NMI), which is used for Tx/Rx of NAN management frames.
- data (NDI), which is used for Tx/Rx of data frames, or non-NAN
  management frames.

The NMI station has two roles:
- representation of the NAN peer - for example, the peer's schedule
  and the HT, VHT, HE capabilities - belong to the NMI station, and not to
  the NDI ones.
- Tx/Rx of NAN management frames to/from the peer.

The NDI station is used for Tx/Rx data frames of a specific NDP that was
established with the NAN peer.

Note that a peer can choose to reuse its NMI address as the NDI address.
In that case, it is expected that two stations will be added even though
they will have the same address.

- An NDI station can only be added after the corresponding NMI station
  was configured with capabilities.
- All the NDI stations will be removed before the NDI interface is brought
  down.
- All NMI stations will be removed before NAN is stopped.
- Before NMI sta removal, all corresponding NDI stations will be removed

Add support for adding, removing, and changing NMI and NDI stations.

bd11c96604 wifi: cfg80211: separately store HT, VHT and HE capabilities for NAN 
In NAN, unlike in other modes, there is only one set of (HT, VHT, HE)
capabilities that is used for all channels (and bands) used in the NAN
data path.

This set of capabilities will have to be a special one, for example - have
the minimum of (HT-for-5 GHz, HT-for-2.4 GHz), careful handling of the
bits that have a different meaning for each band, etc.

While we could use the exiting sband/iftype capabilities, and require
identical capabilities for all bands (makes no sense since this means
that we will have VHT capabilities in the 2.4 GHz slot),
or require that only one of the sbands will be set,
or have logic to extract the minimum and handle the conflicting bits -
it seems simpler to add a dedicated set of capabilities which is special
for NAN, and is band agnostic, to be populated by the driver.

That way we also let the driver decide how it wants to handle the
conflicting bits.

Add this special set of these capabilities to wiphy:nan_capabilities, to be
populated by the driver.
Send it to user space.

0e8ec738a7 wifi: cfg80211: add support for NAN data interface 
This new interface type represents a NAN data interface (NDI).
It is used for data communication with NAN peers.

Note that the existing NL80211_IFTYPE_NAN interface, which is the NAN
Management Interface (NMI), is used for management communication.

An NDI interface is started when a new NAN data path is about to
be established, and is stopped after the NAN data path is terminated.

- An NDI interface can only be started if the NMI is running, and NAN is
  started.
- Before the NMI is stopped, the NDI interfaces will be stopped.

Add the new interface type, handle add/remove operations for it,
and makes sure of the conditions above.

6e78b70c9a wifi: cfg80211: Add an API to configure local NAN schedule 
Add an nl80211 API to allow user space to configure the local NAN
schedule.
The local schedule consists of a list of channel definitions and a schedule
map, in which each element covers a time slot and indicates on what
channel the device should be in that time slot.

Channels can be added to schedule even without being scheduled, for
reservation purposes.

A schedule can be configured either immedietally or be deferred, in case
there are already connected peers.
When the deferred flag is set, the command is a request from the device
to perform an announced schedule update: send the updated NAN
Availability - as set in this command - to the peers, and do the
actual switch to the new schedule on the right time (i.e. at the end of
the slot after the slot in which the update was sent to the peers).
In addition, a notification will be sent to indicate a deferred update
completion.

b008f28600 wifi: iwlwifi: mld: update the TLC when we deactivate a link 
We hit a problem in the channel switch flow.
We had link 0 using PHY 0, so the TLC object in the firmware is using
PHY 0.
Then we switched channel, so mac80211 / iwlmld:
* deactivated link 0
* removed PHY 0
* added PHY 1
* modified link 0 to use PHY 1
* activated link 0.

The TLC object was not updated and the firmware was unhappy that the TLC
was still trying to use PHY 0.

Fix that by letting the TLC know about the PHY context before the link
activation.
When we are de-activating a link, let the TLC know so that it'll send a
TLC configuration command with an invalid PHY context to remove the
relationship between the TLC object and the PHY that is going to be
removed.

That last part is not implemented yet in the firmware, so leave this as
a TODO for now.

4f1da5cf31 wifi: iwlwifi: mld: always assign a fw id to a vif 
We used to have a fw id assignment in iwl_mld_init_vif since all interface
types that were added to the driver was immediately added to the FW as
well.
Since NAN was introduced, this is no longer the case - the NAN interface
is not added to the fw until a local schedule is configured.

For this vif we don't assign a fw id so it is 0 by default.
But later, when the vif is removed from the driver, we think that it has
a valid fw id (0) and we point fw_id_to_vif[0] to NULL.
fw_id_to_vif[0] might actually point to another vif with a valid fw id
0. In this case, we end up messing fw_id_to_vif.

Fix this by initializing a vif with a special invalid fw id, and by
exiting iwl_mld_rm_vif early for NAN interfaces.

ab97a6c94c wifi: iwlwifi: mld: use the dedicated helper to extract a link 
There is a helper, iwl_mld_fw_id_to_link_conf, that converts a fw link
id into the bss_conf structure. Use it in two more places instead of
retrieving the bss_conf directly from the fw-id-to-bss_conf mapping array.

This required changing the loop bound in iwl_mld_process_per_link_stats()
to ucode_capa.num_links, to avoid hitting a IWL_FW_CHECK for link ids
> ucode_capa.num_links and < ARRAY_SIZE(fw_id_to_bss_conf), but this
change makes sense anyway (there is no reason to iterate links that
cannot be valid).

62e4d33c7d wifi: iwlwifi: add MAC context command version 4 
Due to NAN additions, this command needs to grow. In iwlmvm
we just need to use the old _v3 (or v2) version, but iwlmld
needs to handle the difference and send both.  Do that as a
first step towards adding NAN support.
