wifi: cfg80211: handle DFS per link
Currently, during starting a radar detection, no link id information is
parsed and passed down. In order to support starting radar detection
during Multi Link Operation, it is required to pass link id as well.
Add changes to first parse and then pass link id in the start radar
detection path.
Additionally, update notification APIs to allow drivers/mac80211 to
pass the link ID.
However, everything is handled at link 0 only until all API's are ready to
handle it per link.

wifi: trace: unlink rdev_end_cac trace event from wiphy_netdev_evt class
rdev_end_cac trace event is linked with wiphy_netdev_evt event class.
There is no option to pass link ID currently to wiphy_netdev_evt class.
A subsequent change would pass link ID to rdev_end_cac event and hence
it can no longer derive the event class from wiphy_netdev_evt.
Therefore, unlink rdev_end_cac event from wiphy_netdev_evt and define it's
own independent trace event. Link ID would be passed in subsequent change.

Add a regulatory flag to allow VLP AP operation even on

in some regulatory domains/countries.
Note that this requires checking also when the beacon is
changed, since that may change the regulatory power type.

wifi: cfg80211: add support for link id attribute in NL80211_CMD_DEL_STATION
Currently whenever NL80211_CMD_DEL_STATION command is called without any
MAC address, all stations present on that interface are flushed.
However with MLO there is a need to flush such stations only which are
using at least a particular link from the AP MLD interface.
For example - 2 GHz and 5 GHz are part of an AP MLD.
To this interface, following stations are connected -
1. One non-EHT STA on 2 GHz link.
2. One non-EHT STA on 5 GHz link.
3. One Multi-Link STA having 2 GHz and 5 GHz as active links.
Now if currently, NL80211_CMD_DEL_STATION is issued by the 2 GHz link
without any MAC address, it would flush all station entries. However,
flushing of station entry #2 at least is not desireable since it
is connected to 5 GHz link alone.
Hence, add an option to pass link ID as well in the command so that if link
ID is passed, stations using that passed link ID alone would be flushed
and others will not.
So after this, station entries #1 and #3 alone would be flushed and #2 will
remain as it is.

Aloka originally suggested that puncturing should be part of

disagreed and it ended up not part of the chandef, but I've
now realized that this was wrong. Even for clients, the RX,
and perhaps more importantly, CCA configuration needs to take
puncturing into account.
Move puncturing into the chandef, and adjust all the code
accordingly. Also add a few tests for puncturing in chandef

Declaration is '.. c:function:: void cfg80211_rx_assoc_resp (struct net_device *dev, struct cfg80211_rx_assoc_resp *data)'.
This is because there's a function named cfg80211_rx_assoc_resp() and a struct
named cfg80211_rx_assoc_resp, see previous patch for more info.
To workaround this rename the struct to cfg80211_rx_assoc_resp_data. The

Direct replacement is safe here since WIPHY_ASSIGN is only used by
TRACE macros and the return values are ignored.

wifi: nl80211: add a command to enable/disable HW timestamping
Add a command to enable and disable HW timestamping of TM and FTM
frames. HW timestamping can be enabled for a specific mac address
or for all addresses.
The low level driver will indicate how many peers HW timestamping
can be enabled concurrently, and this information will be passed
to userspace.

Add support to offload OWE processing to user space for MLD AP when
driver's SME in use.
Add new parameters in struct cfg80211_update_owe_info to provide below
information in cfg80211_update_owe_info_event() call:
- MLO link ID of the AP, with which station requested (re)association.
This is applicable for both MLO and non-MLO station connections when
the AP affiliated with an MLD.
- Station's MLD address if the connection is MLO capable.

wifi: cfg80211: Authentication offload to user space for MLO connection in STA mode
Currently authentication request event interface doesn't have support to
indicate the user space whether it should enable MLO or not during the
authentication with the specified AP. But driver needs such capability
since the connection is MLO or not decided by the driver in case of SME
offload to the driver.
Add support for driver to indicate MLD address of the AP in
authentication offload request to inform user space to enable MLO during
authentication process. Driver shall look at NL80211_ATTR_MLO_SUPPORT
flag capability in NL80211_CMD_CONNECT to know whether the user space
supports enabling MLO during the authentication offload.
User space should enable MLO during the authentication only when it
receives the AP MLD address in authentication offload request. User
space shouldn't enable MLO if the authentication offload request doesn't
indicate the AP MLD address even if the AP is MLO capable.
When MLO is enabled, user space should use the MAC address of the
interface (on which driver sent request) as self MLD address. User space
and driver to use MLD addresses in RA, TA and BSSID fields of the frames
between them, and driver translates the MLD addresses to/from link
addresses based on the link chosen for the authentication.

wifi: cfg80211: add optional link add/remove callbacks
Add some optional callbacks for link add/remove so that
drivers can react here. Initially, I thought it would be
sufficient to just create the link in start_ap etc., but
it turns out that's not so simple, since there are quite
a few callbacks that can be called: if they're erroneously
without start_ap, things might crash.
Thus it might be easier for drivers to allocate all the
necessary data structures immediately, to not have to
worry about it in each callback, since cfg80211 checks
that the link ID is valid (has been added.)

wifi: cfg80211: do some rework towards MLO link APIs
In order to support multi-link operation with multiple links,
start adding some APIs. The notable addition here is to have
the link ID in a new nl80211 attribute, that will be used to
differentiate the links in many nl80211 operations.
So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID
attribute (as well as the NL80211_ATTR_MLO_LINKS attribute)
and plugs it through the system in some places, checking the
validity etc. along with other infrastructure needed for it.
For now, I've decided to include only the over-the-air link
ID in the API. I know we discussed that we eventually need to
have to have other ways of identifying a link, but for local
AP mode and auth/assoc commands as well as set_key etc. we'll
use the OTA ID.
Also included in this patch is some refactoring of the data
structures in struct wireless_dev, splitting for the first
time the data into type dependent pieces, to make reasoning
about these things easier.

cfg80211: AP mode driver offload for FILS association crypto
Add a driver FILS crypto offload extended capability flag to indicate
that the driver running in AP mode is capable of handling encryption

Add a command to set FILS AAD data to driver.
This feature is supported on drivers running in AP mode only.
This extended capability is exchanged with hostapd during cfg80211
init. If the driver indicates this capability, then before sending the
Authentication response frame, hostapd sets FILS AAD data to the
driver. This allows the driver to decrypt (Re)Association Request
frame and encrypt (Re)Association Response frame. FILS Key derivation
will still be done in hostapd.
