0d2fc8821a wifi: iwlwifi: nvm: parse the VLP/AFC bit from regulatory
6 GHz STA supports different power types as LPI, SP, VLP.
and this information is provided by regulatory info.

Add support in driver to parse the power type capability in
regulatory info from FW and set it to the channel flags.

de0c2cdcb7 wifi: iwlwifi: mvm: limit EHT 320 MHz MCS for STEP URM
If the STEP (the interface between MAC and PHY) is in URM
(a lower speed mode) then we cannot use 320 MHz MCS > 9.
Therefore, limit the MCS in our capabilities in this case.
Note that this also limits the TX/rate scaling since that
takes both TX and RX capabilities into account.

4ea1ed1d14 wifi: iwlwifi: mvm: support set_antenna()
set_antenna() is supported only when the device is not started in
mac80211 which translates to the firmware not being loaded in iwlwifi.

The tricky part is that iwlwifi populates the sband data during its boot
and doesn't touch this data afterwards, but if the antenna settings
forbid MIMO, we need to update the sband data.

Rework the nvm parsing code to allow to get an existing nvm_data and
modify the sband with additional constraints (tx / rx chains masks).

There were are a number of cases in mac80211 and iwlwifi (at
least) that used the sband->iftype_data pointer directly,
instead of using the accessors to find the right array entry

Make sparse warn when such a thing is done.

To not have a lot of casts, add two helper functions/macros

We don't know a reasonable way to detect and work around this problem

In MCC_UPDATE_CMD we get from the FW the number of entries in the
channel info array. We used to WARN_ON if this parameter is greater
than we expected. Since this is not really a driver bug, and since it

Fix this by replacing the WARN_ON with a debug print.

73c289bac0 iwlwifi: propagate (const) type qualifier
Most of this change is a continuation of commit 403ea939ea6a
("iwlwifi: dbg: Mark ucode tlv data as const") propagating the
(const) type qualifier for ucode based tlv data to avoid having
the impression that it is writeable.
The other part of the change preserves the (const) type qualifier
over casts and function calls where it was previously lost.
Both changes are needed to avoid compile time errors on system with
more strict error settings, in this case found with clang on FreeBSD.

55c6d8f89d iwlwifi: support 4-bits in MAC step value
We have a MAC component (which is inside the SoC) and it has several
different HW steps.  3 bits used to be enough but now we need 4-bits
to represent all the different steps.

Properly support 4-bits in the MAC step value by refactoring all the
current handling of the MAC step/dash.

Already from family 8000 and up the dash (bits 0-1) no longer exists
and the step (until 8000 bits 2-3) consists of the dash bits as well.

To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH
macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step
into the trans struct.

In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and
CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro
combining the 2 (this way we don't need shifting or anything else.)

It's easier to use and understand, and to extend for EHT later,

Unfortunately, we need to add _POS so that we can use it in

While at it, fix the typo ("NOMIMAL") which also helps catch any

iwlmei needs to know about the follwing events:

* Association
* De-association
* Country Code change
* SW Rfkill change
* SAR table changes

iwlmei can take the device away from us, so report the new
rfkill type when this happens.
Advertise the required data from the CSME firmware to the
usersapce: mostly, the AP that the CSME firmware is currently
associated to in case there is an active link protection
session.
Generate the HOST_ASSOC / HOST_DISSASSOC messages.

Don't support WPA1 (non-RSNA) for now.
Don't support shared wep either.
We can then determine the AUTH parameter by checking the AKM.
Feed the cipher from the key installation.

SW Rfkill will be implemented later when cfg80211 will
allow us to read the SW Rfkill state.
