6107f30013 wifi: iwlwifi: pass ESR parameters to the firmware 
The firmware needs to know the esr_transtition_timeout to time the
transition between EMLSR and single radio with the AP.
Add the EMLSR support bit to the wiphy extended capabilities so that
it'll be sent in our association request frame. There are some
limitations in the implementation so we cannot use zero
padding/transition delay; fill the correct values.

Also, feed the medium_synchronization delay to the firmware.

fa53608b52 wifi: iwlwifi: mvm: adjust csa notifications and commands to MLO 
In the following notifications and commands mac_id was replaced
with link_id:
* CANCEL_CHANNEL_SWITCH_CMD
* CHANNEL_SWITCH_START_NOTIF
* CHANNEL_SWITCH_ERROR_NOTIF

The logic around was not changed, so only adjust handling
mac/link id.

3f3022694f wifi: iwlwifi: mvm: update the FW apis for LINK and MAC commands 
The firmware added new fields to be able to pass the link_id as the AP
knows it and the esr_transition_timeout.
For now, pass only the link_id since we don't have access to the
esr_transition_timeout yet.

bb7fcb37c9 wifi: iwlwifi: mvm: properly implement HE AP support 
The firmware split the HE support field into HE and "pseudo HE",
the latter is really for AP and doesn't implement trigger frame

Use the new field for AP mode.

d6f6b0d804 wifi: iwlwifi: mvm: add fw link id allocation 
Driver uses link_id as an index in the array. FW currently can

6b5a87df8e wifi: iwlwifi: mvm: align to the LINK cmd update in the FW 
The LINK cmd host api has been updated. Align the driver to the
new changes. Also, temporary use mac_id for link_id.
Using the phy_id as the link_id is wrong since we might have 2 macs
operating on the same phy - in this case we will have 2 different
links (one for each mac) with the same link_id. On the other hand,
since we don't have MLO implemented yet, we won't have 2 different
links of the same mac. Therefore, we can use the mac_id as the
link_id.

ad12b23131 iwlwifi: mvm: offload channel switch timing to FW 
Since FW is now in charge of timing the channel switch, there is no need
to send the add/modify/remove time event command to fw with every (e)CSA
element.
However, the driver needs to cancel the channel switch if the CS start
notification arrives and it does not know about an ongoing channel switch.

86e177d80f iwlwifi: mvm: add NOA and CSA to a probe response 
A probe response built by a P2P GO should contain:
1. CSA/eCSA IE when relevant
2. If the corresponding probe request had P2P IE, then
need to add P2P IE with NOA attributes.

However, the NOA attributes and the updated channel switch
counter are known only to the FW. The solution is that FW
will send a notification with the relevant probe response
data and the driver will save it and update the probe
response accordingly.

d172a5eff6 iwlwifi: reorganize firmware API 
Apart from DVM, all firmware uses the same base API, and there's
code outside iwlmvm that needs to interact with it. Reflect this
in the source better and reorganize the firmware API to a new

While at it, split the already pretty large fw-api.h file into a
number of smaller files, going from almost 3k lines in there to
a maximum number of lines less than 1k.
