To prepare the driver for MLO support, split the driver vif data structure to
scale for multiple links. This requires changing the use of arvif to per link
and not per hw which can now comprise of multiple links. Also since most
configurations from mac80211 are done per link, do refactoring of the driver
functions to apply these configurations at link level.
Split ath12k_vif which is the driver private of ieee80211_vif to store link
specific information as ath12k_link_vif. For default use cases the ath12k vif
will have a preallocated link vif called deflink which will be used by non ML
and the first link vif of ML vif.
With MLO support to be added, remaining link vifs will be allocated during
channel assignment where vdev create/start happens. These link vifs will be
freed during interface down.
Current ath12k_vif(arvif) structure

To refactor existing ath12k_vif to make use of link vifs, following
changes are made:
1. ath12k_vif now called by variable name ahvif storing multiple
arvifs (struct ah12k_link_vif) and also has a back pointer to ieee80211_vif.
2. In this patch set, only deflink is used to be on par with the
existing code. When MLO support is added the link id will be used to fetch
the arvif.
3. For mac80211 ops which doesn't use specific link_id, the config or info
is common for the vif, hence apply the config to all link vifs.
The links_map in the ahvif, will be used to identify all the link vifs that
are setup.
4. Change ath12k_vif_to_arvif() as ath12k_vif_to_ahvif() to fetch the
hw level vif. The link vif can be fetched from ahvif->link[], or the
deflink can be accessed via ahvif->deflink. API to access link
vif (arvif) by passing link_id can be introduced with MLO Support.
5. The ieee80211_vif can be accessed from ahvif using ath12k_ahvif_to_vif().
The locking continues to use wiphy_lock() for protecting access to most data in
struct ath12k&co, there are no changes in that regard. Though struct
ath12k_vif::link[] is protected with RCU.

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.

Currently, the firmware returns incorrect pdev_id information in
WMI_PDEV_BSS_CHAN_INFO_EVENTID, leading to incorrect filling of
the pdev's survey information.
To prevent this issue, when requesting BSS channel information
through WMI_PDEV_BSS_CHAN_INFO_REQUEST_CMDID, firmware expects
pdev_id as one of the arguments in this WMI command.
Add pdev_id to the struct wmi_pdev_bss_chan_info_req_cmd and fill it
during ath12k_wmi_pdev_bss_chan_info_request(). This resolves the
issue of sending the correct pdev_id in WMI_PDEV_BSS_CHAN_INFO_EVENTID.

Currently, the Rx data path only supports parsing peer metadata of version
zero. However, the QCN9274 platform configures the peer metadata version
as V1B. When V1B peer metadata is parsed using the version zero logic,
invalid data is populated, causing valid packets to be dropped. To address
this issue, refactor the peer metadata version and add the version based
parsing to populate the data from peer metadata correctly.

With WoWLAN enabled and after sleeping for a rather long time,
we are seeing that with some APs, it is not able to wake up
the STA though the correct wake up pattern has been configured.
This is because the host doesn't send keepalive command to
firmware, thus firmware will not send any packet to the AP and
after a specific time the AP kicks out the STA.
So enable keepalive before going to suspend and disable it after
resume back.

The survey dump statistics does not display channel RX and TX time
properly because the survey flag is not enabled in the firmware service
flag.
If firmware supports enable the service flag "bss_chan_info" in
wmi_resource_config to fetch and print the stats for specific pdev.
Enabling WMI_RSRC_CFG_FLAG1_BSS_CHANNEL_INFO_64 does not have any impact
on WCN7850 since this bit is not utilized by the WCN7850 firmware.

Due to an error during rebasing the patchset 320 MHz channel support got
broken. ath12k was setting the QoS bit instead of the correct flag.
WMI_PEER_EXT_320MHZ (0x2) is defined as an extended flag, replace
peer_flags by peer_flags_ext while sending peer data.

For P2P mode, the WLAN interface may be requested to remain on a
specific channel and then to send some management frames on that
channel. Now chananel frequency of wmi_mgmt_send_cmd is set as 0. As
a result, firmware may choose a default but wrong channel.
Fix it by assigning chanfreq field with the ROC channel frequency.
This change only applies to WCN7850, other chips are not affected.

In segment memory mode, firmware allocates memory segments of size
2 MB. This 2 MB memory is used by firmware for the number of peers.
This number of peer is sent from host to firmware during WMI init
command. For single-phy the number of peers sent is
TARGET_NUM_PEERS_SINGLE = 529 (512 + 17). While for split-phy number
of peers sent to firmware is TARGET_NUM_PEERS_DBS = 2 *(512 + 17) =
1058. With this 1058 number of peers firmware is unable to allocate
memory in 2 MB segment and firmware crash is observed.
Hence, fix this firmware crash by reducing the number of stations
TARGET_NUM_STATIONS for split-phy.
