29df2a6481 wifi: iwlwifi: mvm: use the link sta address 
Replace the deflink.addr with the proper link address
for setting the peer_link_address in the station command.
For a non-MLD station, it will be the deflink.

b7e39d565f wifi: iwlwifi: mvm: use STA link address 
For now we only support a single link, so just use the
deflink's address for the link address, instead of the
STA's (MLD) address, but use the link address anyway
in order to facilitate MLO connections.

d6f6b0d804 wifi: iwlwifi: mvm: add fw link id allocation 
Driver uses link_id as an index in the array. FW currently can
support only 2 concurrently active links per vif with the ids in the
range 0-3. Add a mapping of dirver link ids to fw link id and track the
number of active link ids.

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.

5ed461be3c wifi: iwlwifi: mvm: always use the sta->addr as the peers addr 
Currently we're setting the sta->addr as the peers address only if
the iftype is NL80211_IFTYPE_AP, otherwise we are setting the bssid to
be the addr. This causes bugs in TDLS. Fix this by always using the
sta->addr.

except for the commands that are being sent during this flows.
Instead of checking each time before calling these floews
what API we use and then call the correct function, call always the old
one, which in turn will call the new one in case we're using the MLD
API.

650cadb730 wifi: iwlwifi: mvm: vif preparation for MLO 
In MLO, some fields of iwl_mvm_vif should be defined in the
context of a link. Define a separate structure for these fields and
add a deflink object to hold it as part of iwl_mvm_vif. Non-MLO legacy
code will use only deflink object while MLO related code will use the
corresponding link from the link array.

It follows the strategy applied in mac80211 for introducing MLO
changes.

The below spatch takes care of updating all driver code to access
fields separated into MLD specific data structure via deflink (need
to convert all references to the fields listed in var to deflink.var
and also to take care of calls like iwl_mvm_vif_from_mac80211(vif)->field).
