092197f1f4 wifi: mac80211: remove/avoid misleading prints
At some point a few kernel debug prints started appearing which
indicated something was sending invalid IEs:

"bad VHT capabilities, disabling VHT"
"Invalid HE elem, Disable HE"

Turns out these were being printed because the local hardware
supported HE/VHT but the peer/AP did not. Bad/invalid indicates,
to me at least, that the IE is in some way malformed, not missing.

For the HE print (ieee80211_verify_peer_he_mcs_support) it will
now silently fail if the HE capability element is missing (still
prints if the element size is wrong).

For the VHT print, it has been removed completely and will silently
set the DISABLE_VHT flag which is consistent with how DISABLE_HT
is set.

Commit 6911458dc428 ("wifi: mac80211: mlme: refactor assoc success
handling") moved the per-link setup out of ieee80211_assoc_success() into a
new function ieee80211_assoc_config_link() but missed to remove the unlock
of 'sta_mtx' in case of HE capability/operation missing on HE AP, which
leads to a double unlock:

ieee80211_assoc_success() {
    ...
    ieee80211_assoc_config_link() {
        ...
        if (!(link->u.mgd.conn_flags & IEEE80211_CONN_DISABLE_HE) &&
            (!elems->he_cap || !elems->he_operation)) {
            mutex_unlock(&sdata->local->sta_mtx);
            ...
        }
        ...
    }
    ...

efe9c2bfd1 wifi: mac80211: isolate driver from inactive links
In order to let the driver select active links and properly
make multi-link connections, as a first step isolate the
driver from inactive links, and set the active links to be
only the association link for client-side interfaces. For
AP side nothing changes since APs always have to have all
their links active.

To simplify things, update the for_each_sta_active_link()
API to include the appropriate vif pointer.

This also implies not allocating a chanctx for an inactive
link, which requires a few more changes.

Since we now no longer try to program multiple links to the
driver, remove the check in the MLME code.

acdc3e4788 wifi: mac80211: mlme: assign link address correctly
Right now, we assign the link address only after we add
the link to the driver, which is quite obviously wrong.
It happens to work in many cases because it gets updated
immediately, and then link_conf updates may update it,
but it's clearly not really right.

Set the link address during ieee80211_mgd_setup_link()
so it's set before telling the driver about the link.

81151ce462 wifi: mac80211: support MLO authentication/association with one link
It might seem a bit pointless to do a multi-link operation
connection with just a single link, but this is already a
big change, so for now, limit MLO connections to a single
link.

Extending that to multiple links will require
 * work on parsing the multi-link element with STA profile
   properly, including element fragmentation;
 * checking the per-link status in the multi-link element
 * implementing logic to have active/inactive links to let
   drivers decide which links should be active;
 * implementing multicast RX deduplication;
 * and likely more.

For now this is still useful since it lets us do multi-link
connections for the purposes of testing APIs and the higher
layers such as wpa_supplicant.

6911458dc4 wifi: mac80211: mlme: refactor assoc success handling
Refactor the per-link setup out of ieee80211_assoc_success()
into a new function ieee80211_assoc_config_link().

It looks useless for now to parse the elements again inside
ieee80211_assoc_config_link(), but that will be done with
the link ID in the future.

Refactor ieee80211_prep_channel() to make the link argument
optional and add a conn_flags pointer argument instead, so
that we can later use this for links that don't exist yet
to build the right information for MLO.

For MLO, we will need to build these elements per link, so
factor out the code that does this, returning the capability,
to simplify building the multi-link element in the future.

39d805998c wifi: mac80211: mlme: switch some things back to deflink
With MLO, when we'll disconnect from an AP MLD, we'll just
destroy all the links. Therefore, the only thing we (may)
need to reset is the deflink data, so switch back to that
and adjust the comments accordingly.

4a21a8ae79 wifi: mac80211: mlme: change flags in ieee80211_determine_chantype()
For MLO we'll need to read flags not directly from the link as
it may not even exist yet if we're just setting up flags for
a secondary link before sending the association request, so
pass the incoming conn_flags separately. Also, while at it,
pass the sdata/link separately as for non-tracking now the
link may be NULL.

The functions currently take a link and check data

Remove the regulatory checks, the warnings shouldn't

Rework the sorting of custom elements into the association
request by moving the elements before HT/VHT/HE to each
their own function. While at it, fix the placement of the
ones that should be between VHT and HE.

This doesn't fix the placement of elements that should be
between HE and EHT yet, a similar change might be needed
in the future.

There's some awkward code that really only exists
because we want to optimize the allocation size,
but that's not really all that necessary.

Refactor the code that adds rates to the association
request frame to have a separate function, removing
the goto.
