5f12dd57a0 wifi: mac80211: correct EHT EIRP TPE parsing
For the EHT EIRP transmit power envelope, the 320 MHz is in
the last octet, but if we've copied 4 octets (count == 3),
the next one is at index 4 not 5 (count + 2). Fix this, and
just hardcode the offset since count is always 3 here.

0c2fd18f7e wifi: mac80211: fix Spatial Reuse element size check
Currently, the way to check the size of Spatial Reuse IE data in the
ieee80211_parse_extension_element() is incorrect.

This is because the len variable in the ieee80211_parse_extension_element()
function is equal to the size of Spatial Reuse IE data minus one and the
value of returned by the ieee80211_he_spr_size() function is equal to
the length of Spatial Reuse IE data. So the result of the
len >= ieee80211_he_spr_size(data) statement always false.

To address this issue and make it consistent with the logic used elsewhere
with ieee80211_he_oper_size(), change the
"len >= ieee80211_he_spr_size(data)" to
“len >= ieee80211_he_spr_size(data) - 1”.

39dc8b8ea3 wifi: mac80211: pass parsed TPE data to drivers
Instead of passing the full TPE elements, in all their glory
and mixed up data formats for HE backward compatibility, parse
them fully into the right values, and pass that to the drivers.

Also introduce proper validation already in mac80211, so that
drivers don't need to do it, and parse the EHT portions.

The code now passes the values in the right order according to
the channel used by an interface, which could also be a subset
of the data advertised by the AP, if we couldn't connect with
the full bandwidth (for whatever reason.)

Also add kunit tests for the more complicated bits of it.

4d70e9c548 wifi: mac80211: defragment reconfiguration MLE when parsing
Using the scratch buffer (without advancing it) here in the
mlme.c code seems somewhat wrong, defragment the reconfig
multi-link element already when parsing. This might be a bit
more work in certain cases, but makes the whole thing more
regular.

508c423d94 wifi: mac80211: simplify multi-link element parsing
We shouldn't assign elems->ml_basic{,len} before defragmentation,
and we don't need elems->ml_reconf{,len} at all since we don't do
defragmentation. Clean that up a bit. This does require always
defragmention even when it may not be needed, but that's easier
to reason about.
