4d56037a02 wifi: iwlwifi: mld: block EMLSR during TDLS connections 
TDLS (Tunneled Direct Link Setup) requires single-link operation
for direct peer-to-peer communication, which is incompatible with
EMLSR (Enhanced Multi-Link Single Radio) mode where the radio
switches between multiple links.

Block EMLSR when the first TDLS peer is added and unblock when
the last TDLS peer is removed. The block/unblock APIs handle
exiting EMLSR and triggering link selection automatically.

b008f28600 wifi: iwlwifi: mld: update the TLC when we deactivate a link 
We hit a problem in the channel switch flow.
We had link 0 using PHY 0, so the TLC object in the firmware is using
PHY 0.
Then we switched channel, so mac80211 / iwlmld:
* deactivated link 0
* removed PHY 0
* added PHY 1
* modified link 0 to use PHY 1
* activated link 0.

The TLC object was not updated and the firmware was unhappy that the TLC
was still trying to use PHY 0.

Fix that by letting the TLC know about the PHY context before the link
activation.
When we are de-activating a link, let the TLC know so that it'll send a
TLC configuration command with an invalid PHY context to remove the
relationship between the TLC object and the PHY that is going to be
removed.

That last part is not implemented yet in the firmware, so leave this as
a TODO for now.

f2463eff4a wifi: iwlwifi: add a macro for max FW links

4f1da5cf31 wifi: iwlwifi: mld: always assign a fw id to a vif 
We used to have a fw id assignment in iwl_mld_init_vif since all interface
types that were added to the driver was immediately added to the FW as
well.
Since NAN was introduced, this is no longer the case - the NAN interface
is not added to the fw until a local schedule is configured.

For this vif we don't assign a fw id so it is 0 by default.
But later, when the vif is removed from the driver, we think that it has
a valid fw id (0) and we point fw_id_to_vif[0] to NULL.
fw_id_to_vif[0] might actually point to another vif with a valid fw id
0. In this case, we end up messing fw_id_to_vif.

Fix this by initializing a vif with a special invalid fw id, and by
exiting iwl_mld_rm_vif early for NAN interfaces.

ab97a6c94c wifi: iwlwifi: mld: use the dedicated helper to extract a link 
There is a helper, iwl_mld_fw_id_to_link_conf, that converts a fw link
id into the bss_conf structure. Use it in two more places instead of
retrieving the bss_conf directly from the fw-id-to-bss_conf mapping array.

This required changing the loop bound in iwl_mld_process_per_link_stats()
to ucode_capa.num_links, to avoid hitting a IWL_FW_CHECK for link ids
> ucode_capa.num_links and < ARRAY_SIZE(fw_id_to_bss_conf), but this
change makes sense anyway (there is no reason to iterate links that
cannot be valid).

de985774e2 wifi: iwlwifi: uefi: open code the parsing of the WGDS table 
We will soon add support for UNII-9 band in the WGDS table. We need to
decouple the UEFI code from the firmware runtime code.
The firmware runtime is just a software object which will need to grow
and UEFI objects need a new revision to grow. Existing systems will keep
the same UEFI objects.

Just like PPAG and SAR, stop using structures to parse the UEFI tables
since the layout depends on the revision.
The support for the new revision will be added in the next patch, for
now, just do the ground work.

Those tables now have support for UNII-9 subband.
Refactor iwl_uefi_set_sar_profile to get an array of values that makes
it easier to use when the number of subbands can vary.
Revamp a bit the code that fetches the tables to ask for the smaller
table, then we can check the size of the object that we got and compare
to the expected sizes to determine what revision to expect.

f983c7308e wifi: iwlwifi: uefi: open code the PPAG table store operation 
The structure in firmware runtime will need to grow because we're adding
a subband for UNII-9.
This means that we will soon no longer be able to just memcpy the data
from the UEFI table. The layout of the array will change.
Tediously copy the data byte-byte to make sure things get to the right
place even when we'll increase the number of subbands.
Make it easier for the uefi_cnv_var_ppag structure to grow by
simpiflying the layout it becomes an array of s8.
The layout of the structure becomes less obvious from the structure's
declaration, but then the code is more flexible.

Don't use UEFI_SAR_MAX_SUB_BANDS_NUM for the number of bands for PPAG.
Of course, SAR related structures will grow in future patches, but
decouple SAR and PPAG to make the work easier.
