fe25b1518f iwlwifi: move TH1 devices to the new table
TH1 devices can now be fully differentiated by using the device
parameters we have (particularly the RF_TYPE).  Start using these
parameters instead of hardcoding to specific subsystem device IDs.

This also fixes the name of one of the TH1 devices that was
erroneously using the 9260 struct and renames 9160 to 9162.

b200dba702 iwlwifi: map 9461 and 9462 using RF type and RF ID
These devices can be differentiated depending on the RF type and RF
ID.  Change them to use these instead of relying on the subsystem
device IDs.

This also fixes some names that were not including 160MHz (as they
should).

f673a193d5 iwlwifi: add Pu/PnJ/Th device values to differentiate them
Pu, PnJ and Th devices have different combinations of PCI ID, MAC ID
and RF IDs.  Use these to differentiate them and choose the correct
configuration.

This also includes a change from using soc cfg's for 0x2526
devices (PnJ/Th), which was incorrect.

95939551e2 iwlwifi: add GNSS differentiation to the device tables
Devices that also include a GNSS module have different names, so add a
new device option to differentiate them, according to the values we
have in the modules section of the subsystem device ID.

Additionally, convert the two applicable devices to use this value
instead of hardcoded subsystem IDs.

d6f2134a38 iwlwifi: add mac/rf types and 160MHz to the device tables
Add MAC ID, RF ID and the bit that tells us whether the device can

This allows us to chose the correct structure and string depending on

32521a9138 libertas: Use new structure for SPI transfer delays
In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

9454f7a895 mwifiex: set needed_headroom, not hard_header_len
hard_header_len provides limitations for things like AF_PACKET, such
that we don't allow transmitting packets smaller than this.

needed_headroom provides a suggested minimum headroom for SKBs, so that
we can trivally add our headers to the front.

The latter is the correct field to use in this case, while the former
mostly just prevents sending small AF_PACKET frames.

In any case, mwifiex already does its own bounce buffering [1] if we
don't have enough headroom, so hints (not hard limits) are all that are
needed.

This is the essentially the same bug (and fix) that brcmfmac had, fixed
in commit cb39288fd6 ("brcmfmac: use ndev->needed_headroom to reserve
additional header space").

[1] mwifiex_hard_start_xmit():
	if (skb_headroom(skb) < MWIFIEX_MIN_DATA_HEADER_LEN) {
	[...]
		/* Insufficient skb headroom - allocate a new skb */

616f5701f4 qtnfmac: assign each wiphy to its own virtual platform device
Quantenna Pearl device exposes multiple (up to 3) radio interfaces under
single PCIe function. So far all the wiphy devices were attached to the
same pcie device. As a result, all different wireless network devices
were reported under the same sysfs directory for pcie device, e.g.:

$ ls  /sys/class/net/wlan0/device/net/
  wlan0 wlan1

It turns out that such behavior may confuse various users of wireless
subsystem. For instance, it turned out to be the case for:
- Linux init systems, e.g. for renaming based on parent device
- OpenWRT configuration scripts

Suggested solution is to add an intermediate virtual platform device
for each radio interface.

968ae2caad ath9k: Handle txpower changes even when TPC is disabled
When TPC is disabled IEEE80211_CONF_CHANGE_POWER event can be handled to
reconfigure HW's maximum txpower.

This fixes 0dBm txpower setting when user attaches to an interface for
the first time with the following scenario:

ieee80211_do_open()
    ath9k_add_interface()
        ath9k_set_txpower() /* Set TX power with not yet initialized
                               sc->hw->conf.power_level */

                             raise IEEE80211_CONF_CHANGE_POWER */

    ath9k_config() /* IEEE80211_CONF_CHANGE_POWER is ignored */

This issue can be reproduced with the following:

  $ modprobe -r ath9k
  $ modprobe ath9k
  $ wpa_supplicant -i wlan0 -c /tmp/wpa.conf &
  $ iw dev /* Here TX power is either 0 or 3 depending on RF chain */
  $ killall wpa_supplicant
  $ iw dev /* TX power goes back to calibrated value and subsequent
              calls will be fine */

New version FW will report chip reset service bit to host. Host allow user

For older NON-TLV FW, since it do not report chip reset service bit, host
will not send chip reset command. For older TLV FW, since it report chip

For sdio chip, it need the memory which is kmalloc, if it is
vmalloc from ath10k_mem_value_read, then it have a memory error.
kzalloc of ath10k_sdio_hif_diag_read32 is the correct type, so
add kzalloc in ath10k_sdio_hif_diag_read to replace the buffer
which is vmalloc from ath10k_mem_value_read.

This patch only effect sdio chip.

a4b9f641e8 ath10k: avoid consecutive OTP download to reduce boot time
Currently, OTP is downloaded twice in case of "pre-cal-dt"
and "pre-cal-file" to fetch the board ID and takes around
~2 sec more boot uptime.

First OTP download happens in "ath10k_core_probe_fw" and
second in ath10k_core_start. First boot does not need OTP
download in core start when valid board id acquired.

The second OTP download is required upon core stop/start.

This patch skips the OTP download when first OTP download
has acquired a valid board id. This patch also marks board
id invalid in "ath10k_core_stop", which will force the OTP
download in ath10k_core_start and fetches valid board id.

a483e29ca0 mac80211_hwsim: enable Beacon protection
Now that there is support for BIGTK configuration and AP/STA
functionality for using BIP with Beacon frames, indicate support for the
Beacon protection functionality.

Johannes: move this to hwsim, since it's not clear that all drivers
using mac80211 will do this correctly - lots of them modify the
beacon before transmission e.g. to update the TIM element, and that
would obviously break the signature.

0e544cb59c mt76: mt7615: rework rx phy index handling
Overwriting the RMAC_CHFREQ register is not reliable enough, as the firmware
could potentially write it again.
Since there is no PHY index indication in the rx info, we need to use another
way:

If both PHYs are using different channels, find the PHY where chfreq matches
the register value.

The only corner case remaining is when both PHYs are using the same channel.
In that case, the per-packet noise value on the primary PHY will have
information belonging to the chains of the secondary PHY from the previous
received packet of that PHY. The secondary PHY will set noise to 0 for extra
chains.
