The length check for the BSS Termination Duration subelement was
accidentally removed and this could result in reading up to 10 bytes
beyond the end of a received frame. The actual read bytes would be
stored locally, but they were not used for anything, so other than
reading beyond the end of an allocated heap memory buffer, this did not
result in any behavior difference or exposure of the bytes.

An earlier change in drivers_ops API for struct external_auth broke the
way SSID and BSSID for an external authentication request were stored.
The implementation depended on the memory array being available in the
API struct with a use of memcpy() to copy the full structure even though
when only SSID and BSSID was needed. Fix this by replacing that
easy-to-break storing mechanism with explicit arrays for the exact set
of needed information.

A DPP TCP connection can now be initiated directly from wpa_supplicant

For reassociation with the same AP wpa_supplicant attempts to use cached
PMKSA. For this purpose PMKID is passed in RSNE in (Re)Association
Request frame. In the case of SAE AP, open authentication shall be used
during reassociation. Otherwise cached PMKID becomes invalid after full
SAE authentication.
The previous implementation correctly handles SME-in-wpa_supplicant
cases. However SME-in-driver cases, complete SAE authentication is
performed. As a result, first reassociation attempt fails.
Fix SME-in-driver behavior by reseting authentication algorithm to
WPA_AUTH_ALG_OPEN when reassociating with SAE AP with an existing PMKSA
cache entry.

When FILS authentication is used with ERP, no EAPOL frames are expected
after association. However, for drivers that set the
WPA_DRIVER_FLAGS_4WAY_HANDSHAKE_8021X capability flag, the EAP state
machine was not configured correctly and was waiting for EAPOL frames,
which leads to disconnection.
Fix this by reordering the if branches to set the EAPOL/EAP state
machines to success when FILS authentication was already completed.
