Currently DFS works under assumption there could be only one channel
context in the hardware. Hence, drivers just calls the function
ieee80211_radar_detected() passing the hardware structure. However, with
MLO, this obviously will not work since number of channel contexts will be
more than one and hence drivers would need to pass the channel information
as well on which the radar is detected.
Also, when radar is detected in one of the links, other link's CAC should
not be cancelled.
Hence, in order to support DFS with MLO, do the following changes -
* Add channel context conf pointer as an argument to the function
ieee80211_radar_detected(). During MLO, drivers would have to pass on
which channel context conf radar is detected. Otherwise, drivers could
just pass NULL.
* ieee80211_radar_detected() will iterate over all channel contexts
present and
* if channel context conf is passed, only mark that as radar
detected
* if NULL is passed, then mark all channel contexts as radar
detected
* Then as usual, schedule the radar detected work.
* In the worker, go over all the contexts again and for all such context
which is marked with radar detected, cancel the ongoing CAC by calling
ieee80211_dfs_cac_cancel() and then notify cfg80211 via
cfg80211_radar_event().
* To cancel the CAC, pass the channel context as well where radar is
detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is
canceled only on the links using the provided context, leaving other
links unaffected.
This would also help in scenarios where there is split phy 5 GHz radio,
which is capable of DFS channels in both lower and upper band. In this
case, simultaneous radars can be detected.

This caused sparse warnings, and clearly is needed per

This event is used by the Firmware to limit the RX BA win size
for a specific link.
The event handler updates the new size in the mac's sta->sta struct.
BA sessions opened for that link will use the new restricted
win_size. This limitation remains until a new update is received or
until the link is closed.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

Add debugfs key (under CFG80211_CERTIFICATION_ONUS
configuration) to set/clear radar_debug_mode.
In this mode, the driver simply ignores radar
events (but prints them).
The fw is notified about this mode through
a special generic_cfg_feature command.
This mode is relevant only for ap mode. look for
it when initializing ap vif.

Enable the FW Logger to work over the SDIO interface in addition to over UART
interface. In the new design we use fw internal memory instead of packet ram
that was used in older (wl12xx) design. This change reduces the impact on TP
and stability.
A new event was added to notify fw logger is ready for reading. Dynamic
configuration to debugfs was added as well.

This modifies cfg80211_vendor_event_alloc() with an additional argument
struct wireless_dev *wdev. __cfg80211_alloc_event_skb() is modified to
take in *wdev argument, if wdev != NULL, both the NL80211_ATTR_IFINDEX
and wdev identifier are added to the vendor event.
These changes make it easier for drivers to add ifindex indication in
vendor events cleanly.
This also updates all existing users of cfg80211_vendor_event_alloc()
and __cfg80211_alloc_event_skb() in the kernel tree.

FW API changed and now PERIODIC_SCAN_REPORT_EVENT is sent
in case results were found at the end of each sched scan
cycle. Previous FW was missing that and broke sched scan.

In 18xx the calibration process of the PHY Cortex domain
requires to perform an active calibration of the channel
before it can be used for transmission. To fulfill world
wide regulatory restrictions, fw should be always
synchronized/updated with current CRDA configuration.
Add a new "CMD_DFS_CHANNEL_CONFIG" command to update the
fw with current reg-domain, this command passes a bit map
of channels that are allowed to be used for transmission.
The driver shall update the fw during initialization and
after each change in the current reg-domain
configuration. The driver will save the channel number of
incoming beacons during the scan process, as they might
be a result of the passive scan on
"IEEE80211_CHAN_PASSIVE_SCAN" channel and will update the
fw accordingly once the scan is finished, the purpose of
this is to be ready in case of the authentication request
on one of these disabled (uncalibrated) channels.
The new command requires to wait for the fw completion
event "DFS_CHANNELS_CONFIG_COMPLETE_EVENT".
No scan commands (including the sched scan) can be
executed concurrently with the "CMD_DFS_CHANNEL_CONFIG",
wl->mutex ensures that.

The event mailbox in wl18xx has a different
(non-compatible) structure.
Create common functions in wlcore to handle the
events, and call them from the chip-specific
event mailbox parsers.
This way, each driver (wl12xx/wl18xx) extracts
the event mailbox by itself according to its
own structure, and then calls the common
wlcore functions to handle it.
