Prefer a BSS entry that has a matching STA entry when processing
EAPOL-Key frames. This avoids issues where some combination of MLD
and/or link addresses are used in a sequence that could end up
generating two separate STA entries for the same non-AP MLD.

When I was testing dpp_auth_init on an AP with Enrollee on a different
channel from the AP I was getting failures. This happened on hwsim in
UML with time-travel for me. I don't recall seeing this with real
devices, presumably because of lax offchan implementation.
The DPP authentication would succeed. However the station would then try
to get configuration through a GAS request and fail.
The AP reported the following logs (grepped):
> 1614762426.860212: RX_ACTION category 4 action 10 sa 02:00:00:00:01:00 da 02:00:00:00:00:00 len 227 freq 2412

When MAC address randomization settings change we should use a new MAC
address even if we are associating to the same ESS.
For example, consider this scenario:
- hardware MAC is being used,
- we disconnect from the network,
- policy/style is changed via D-Bus to turn randomization on,
- we reconnect to the same network.
In the last step a randomized MAC address should be used.
Changes to the randomization settings include both changes to the
policy/style to be used and changes to the pregenerated MAC address
value in case of mac_addr==3.

gas_failures was using an invalid preassoc_mac_addr value 1111 to

sta_dynamic_random_mac_addr and sta_dynamic_random_mac_addr_keep_oui

accident, but set this properly to configure a longer lifetime.

If the CreateInterface command was used to create a virtual AP
interface, deleting this interface using the RemoveInterface command was
also bringing down the primary interface.
wpa_supplicant never uses hostapd style multi-BSS setup with
type=WPA_IF_AP_BSS and setup_ap=1 to if_add() when creating an AP
interface in wpa_driver_nl80211_if_add(), so it should not go through
the multi-BSS tear down procedure in wpa_driver_nl80211_if_remove(). The
virtual AP resources init and deinit are well handled in
wpa_driver_nl80211_init() and wpa_driver_nl80211_deinit().
Collapse the interface type to WPA_IF_STATION for the D-Bus interface to
skip the multi-BSS cleanup procedure. This is inline with the control
interface design. Add comments before the code to avoid confusion.

Authentication frames include several fixed body parts (see Table 9-68
(Authentication frame body) and Table 9-69 (Presence of fields and
elements in Authentication frames) in IEEE P802.11-REVme/D2.0).
To be able to parse the IE part, these fields need to be skipped. Since
SAE logic already implements this parsing, change SAE authentication
handling functions to return the offset to the IE part. This preparation
is needed for future MLD patches that need to parse out the ML related
elements in the Authentication frames.

When AP is started on a DFS channel and DFS is offloaded to the driver,
AP setup will be separated to two stages. In the first stage, hostapd
will set frequency and initialize BSS, then waits the driver CAC to
complete. Once CAC done, in the second stage,
hostapd_setup_interface_complete() will be called again from a callback
to continue AP/channel setup.
But the driver will fail to restart AP if it is disabled/reenabled
during a driver CAC procedure because some steps such as setting
freq/beacon in the first stage are skipped due to cac_started not
cleared when the AP is disabled.
Avoid this by clearing cac_started when the AP is disabled.
