When AP goes down or too far away without indication to STA, beacon miss
will be detected. Then for WCN7850's firmware, it will use roam event
to send beacon miss to host.
If STA doesn't handle the beacon miss, will keep the fake connection
and unable to roam.
So add support for WCN7850 to trigger disconnection from AP when
receiving this event from firmware.
It has to be noted that beacon miss event notification for QCN9274
to be handled in a separate patch as it uses STA kickout WMI event
to notify beacon miss and the current STA kickout event is processed
as low_ack.

Every time EHT Operation element changed, mac80211 will parse it and
extract the valid puncturing bitmap according to the bandwidth.
Current driver only update puncturing bitmap to firmware as vdev
parameter. Which can only meet the needs of AP. But STA will also use
it as peer parameter. If only update as vdev parameter, might cause
firmware crash. QCN9274 is the same.
So update bandwidth and puncturing bitmap as peer parameters once they

Most of the RX descriptors fields are currently not used in the
ath12k driver. Hence add support to selectively subscribe to the
required quad words (64 bits) within msdu_end and mpdu_start of
rx_desc.
Add compact rx_desc structures and configure the bit mask for Rx TLVs
(msdu_end, mpdu_start, mpdu_end) via registers. With these registers
SW can configure to DMA the partial TLV struct to Rx buffer.
Each TLV type has its own register to configure the mask value.
The mask value configured in register will indicate if a particular
QWORD has to be written to rx buffer or not i.e., if Nth bit is enabled
in the mask Nth QWORD will be written and it will not be written if the
bit is disabled in mask. While 0th bit indicates whether TLV tag will be
written or not.
Advantages of Qword subscription of TLVs
- Avoid multiple cache-line misses as the all the required fields
of the TLV are within 128 bytes.
- Memory optimization as TLVs + DATA + SHINFO can fit in 2k buffer
even for 64 bit kernel.

flags are defined as macros, and are named WMI_PEER_*. The last three
macros have the same name as the last three wmi_tlv_peer_flags

The code only uses the WMI_PEER_* names; the WMI_TLV_PEER_* names are
unused. So as a first step in consolidation, remove all the
WMI_TLV_PEER_* names.
But since having an enum to define all the flags is actually a good

In a special WCN7855 firmware release the EHT (IEEE 802.11be) support has
been disabled for size reduction. Currently ath12k always enables EHT PHY
mode during vdev start but with the special firmware that will cause a
firmware crash during vdev start in firmware initialisation. This is
because the firmware will use the EHT mode to allocate resources but as
the EHT mode is not available in the firmware, there's an internal
conflict and the firmware will crash.
To fix the crash check the WMI_TLV_SERVICE_11BE flag to see if the firmware
supports EHT. If EHT is not supported downgrade the PHY mode to HE
(IEEE 802.11ax).
This does not impact QCN9274, because WMI_SERVICE_11BE is always enabled
for QCN9274, then eht_cap->has_eht will always set for it, and the logic
of this patch will not take effect and the PHY mode will not down grade
for it.

For single_pdev chip such as WCN7850, only one pdev is created
and only one hardware is registered to mac80211. This one pdev
manages both 2.4 GHz radio and 5 GHz/6 GHz radio.

Currently there are about 60 channels for 6 GHz, then the size of
chan_list in struct scan_req_params which is 40 is not enough to
fill all the channel list of 6 GHz.
Use dynamic memory to save the channel list of scan.

In order to support different power levels of 6 GHz AP and client, new WMI
event for regulatory (WMI_REG_CHAN_LIST_CC_EXT_EVENTID) has been added in
firmware to provide new parameters required for 6 GHz regulatory rules.
Firmware advertises its capability of handling new event in WMI service ready
event. Based on that, host needs to set host_service_flags in WMI init command
to indicate that host supports processing of this WMI event. Based on
advertised host capability, firmware sends event WMI_REG_CHAN_LIST_CC_EXT_EVENTID.
This new event contains 2G/5G/6G reg rules with additional power value fields
for 6GHz and regd is built accordingly.

When vdev start/stop happens, response from firmware is received with delay
and hence there is a timeout before VDEV can be up/down.
Also, with maximum peers connected and when vdev stop occurs, firmware
will take time to clean up all the peers and vap queues.
In such cases as well, vdev start/stop response is sent by firmware with delay.
Increase the vdev setup timeout as recommended by firmware team.

Both PSOC_HOST_MAX_NUM_SS and WMI_MAX_NUM_SS are set to 8. The host assumes
that the values are the same but there's no check for that, so things will
break if either of the values change. It's simpler and safer to have just one
define so delete PSOC_HOST_MAX_NUM_SS and use WMI_MAX_NUM_SS everywhere.
No functional changes.

ath12k is a new mac80211 driver for Qualcomm Wi-Fi 7 devices, first
supporting QCN9274 and WCN7850 PCI devices. QCN9274 supports both AP
and station; WCN7850 supports only station mode. Monitor mode is not
(yet) supported. Only PCI bus devices are supported.
ath12k is forked from an earlier version of ath11k. It was simpler to
have a "clean start" for the new generation and not try to share the
code with ath11k. This makes maintenance easier and avoids major
changes in ath11k, which would have significantly increased the risk
of regressions in existing setups.
ath12k uses le32 and cpu_to_le32() macros to handle endian
conversions, instead of using the firmware byte swap feature utilized
by ath11k. There is only one kernel module, named ath12k.ko.
Currently ath12k only supports HE mode (IEEE 802.11ax) or older, but
work is ongoing to add EHT mode (IEEE 802.11be) support.
The size of the driver is ~41 kLOC and 45 files. To make the review
easier, this initial version of ath12k does not support Device Tree,
debugfs or any other extra features. Those will be added later, after
ath12k is accepted to upstream.
The driver is build tested by Intel's kernel test robot with both GCC
and Clang. Sparse reports no warnings. The driver is mostly free of
checkpatch warnings, albeit few of the warnings are omitted on
purpose, list of them here:
https://github.com/qca/qca-swiss-army-knife/blob/master/tools/scripts/ath12k/ath12k-check#L52
The driver has had multiple authors who are listed in alphabetical
order below.
