The CCK TX setting when switch channel will fix the CCK to
path A only, so if the antenna is configured to path B
(e.g. iw phy set antenna 0x2 0x3 "TX B/RX AB"), then the CCK
packets can never be delivered to the air if only path B is
connected with an antenna (it can possibly be transmitted
through path A, but as path B is configured, the expected
behavior is incorrect).
This can also solve the racing issue of CCK TX setting between
driver and firmware. The CCK TX setting in driver should be
removed. Otherwise, the CCK TX setting would be wrong when the
racing occurs.

Connecting to an AP with WPA2 security may fail. The IQK
and the EAPOL 4-way handshake may overlap because the
driver does IQK right after assoc success.
For 802.11n devices, the IQK is done in the driver and it
could require more than 100ms to complete. During IQK, any
TX/RX events are paused. So if the EAPOL 4-way handshake
started before IQK finished, then the 1/4 and 2/4 part of
the handshake could be dropped. The AP will then issue
deauth with reason IEEE8021X_FAILED (23).
To resolve this, move IQK routine into managed TX prepare
(ieee80211_ops::mgd_prepare_tx()). The callback is called
before the managed frames (auth/assoc) are sent. This will
make sure that the IQK is completed before the handshake
starts. But don't do IQK during scanning because doing it
on each channel will take too long.
For 802.11ac devices, the IQK is done in firmware and it
takes less time to complete. Therefore we don't see a
failure during the EAPOL 4-way handshake. But it is still
worth moving the IQK into ieee80211_ops::mgd_prepare_tx().

Since the driver was first introduced into the kernel, it has only
handled the ciphers associated with WEP, WPA, and WPA2. It fails with
WPA3 even though mac80211 can handle those additional ciphers in software,
b43legacy did not report that it could handle them. By setting MFP_CAPABLE using
ieee80211_set_hw(), the problem is fixed.
With this change, b43legacy will handle the ciphers it knows in hardware,
and let mac80211 handle the others in software. It is not necessary to
use the module parameter NOHWCRYPT to turn hardware encryption off.
Although this change essentially eliminates that module parameter,
I am choosing to keep it for cases where the hardware is broken,
and software encryption is required for all ciphers.

This reverts commit 07d0f55349.
For rtw88 driver, the SDIO is going to be supported, so there is
no need to remove the SDIO related power sequence settings. And
while the power sequence parser will pass in the mask of the HCI,
the SDIO part will not be used to set registers accordingly.
Moreover, the power sequence table is released as a whole package,
so the next time if we are going to update, the SDIO settings will
be overwritten. So, revert this now.

Also replace generic MANUFACTURER macros by proper SDIO IDs macros.
Checks for device IDs are slightly modified to use SDIO device IDs.
This allows removal of all custom MANUFACTURER macros from ath10k.

Add _WLAN suffix to macro names for consistency with other Marvell macros.
These IDs represents wlan function of combo bt/wlan cards. Other functions
of these cards have different IDs.

Range request version 10 keeps the same command size as version 9
but uses 2 reserved fields for the responder beacon interval and
station id (if exists).
For now, since the beacon interval of unassoc APs is unknown, use
a value of 100 TUs which is a common value for many APs.
While at it, remove the definition for CCMP_256 cipher, since this
is not supported.

We don't want to have txq code in the PCIe transport code, so move all
the relevant elements to a new iwl_txq structure and store it in
iwl_trans.

Newer firmware versions will parse a few extra bits in the
context info to be able to determine whether we are using
bigger than 4k RBs, indicate 8k/12k to them if we actually
use those (e.g. for sniffer based on the module parameter).

ACPI Device Specific Method (DSM) allows standardized feature
configuration through the ACPI interface without the namespace
pollution of the usual mechanism (ACPI method for each feature).
Add generic function for evaluating DSM objects and function for
evaluating a DSM with no arguments and a single int return value.
also implement the required backport for UUID.
