For WPA3 SAE LFR-3.0 roaming, authentication is offloaded to the
wpa_supplicant via the host driver due to the target crypto
inavailability limitations. The target does candidate selection
and sends the WMI_ROAM_PREAUTH_START_CMDID to the driver.
Once the SAE authentication is done, the supplicant sends the
external auth NL command with the authentication status, PMKID
derived. On receiving this event, send the PMKID, bssid, auth
status to the target over WMI_ROAM_PREAUTH_STATUS_CMDID command.
The host driver decides if the external authentication event is
received for preauth candidate or for initial connection by
checking the connected state information of the csr session.
When the authentication fails with the first candidate, the
target triggers the preauth start for the next candidate. This
happens till there are no candidates available to roam.
There could be a situation where the firmware sends preauth
event for candidate1 and before the supplicant could send the
external auth command to the host driver, the candidate1 preauth
timer could have expired and firmware sends the preauth start for
second candidate. After SAE is done with second candidate also,
the supplicant sends external auth event for second candidate. So
in this situation the firmware should decide to choose the
latest candidate. The host driver here is a mere passthrough and
doesn't maintain timer for the preauth event for each BSSID to
drop the expired candidate preauth events.

The Linux Coding Style frowns upon mixed-case names so rename
identifier tpAddBssParams to be compliant.
The Linux Coding Style enumerates a few special cases where typedefs
are useful, but stresses "NEVER EVER use a typedef unless you can
clearly match one of those rules." The tAddBssParams typedef does
not meet any of those criteria, so replace it (and the "tp" variant)
with a properly named struct.

Firmware offloads WPA3 SAE authentication to host due to the
crypto library availability limitation. Once the roam candidate
selection is done in the firmware, firmware sends the
WMI_ROAM_PREAUTH_START_EVENTID. Once this event is received, the
host driver triggers the SAE.
Add support to offload the SAE authentication from firmware to
wpa_supplicant.

The host driver drops any authentication frames that doesn't
belong to current pe session. But, for WPA3 SAE roaming
pre-authentication is offloaded to user space, and as part of
that, the host driver should handle the SAE commit/confirm
messages received from the target AP for which there is no
pe_session.
Add changes to check the auth algorithm in the authentication
frames received for which no pe_session exist and if auth algo is
SAE, indicate that frame to wpa_supplicant.

Currently driver passes sta_id through out the call for getting the TSM
stats. Although passed, the sta_id is not used anywhere in the call
stack. As part of removing the sta_id usage, this sta_id can also be
removed safely.
Remove the usage of sta_id in get TSM stats path.
