79f3121bb4 FILS: Set cache identifier in current PMKSA entry for driver-SME case
This was already done in sme_send_authentication() for the case where
wpa_supplicant SME is used. Similar change is needed for driver-SME to
allow FILS authentication to be offloaded to the driver.

3d5f0e916d wpa_supplicant: Avoid associating to temp disabled SSID in ap_scan=2
In ap_scan=2 mode, wpa_supplicant_assoc_try() did not check whether the
SSID is temporarily disabled before trying to associate and this may
result in an infinite connect/disconnect loop. If the association
succeeds while the SSID is temporarily disabled, wpa_supplicant will
request to deauthenticate and that in turn will cause the SSID to be
temporarily disabled again. Fix that by postponing the association until
the SSID is no longer temporarily disabled.

13bf18eda5 WNM: Use a dynamically allocated buffer for BTM query and response
BSS transition management query and response use a large static buffer
for the frame because the candidate list may require a lot of space.
However, in most cases the actually used space will be much less than
the buffer (since the candidate list is short or completely missing).

Use a dynamically allocated buffer instead and allocate it according
to the actual space needed.

While at it, remove unneeded filling of the MAC header in the Action
frames, since this gets ignored and wpa_drv_send_action() adds the MAC
header anyway.
