This commit introduces a threshold for OWE transition BSS selection,
which signifies the maximum number of selection attempts (scans) done
for finding OWE BSS.
This aims to do more scan attempts for OWE BSS and eventually select the
open BSS if the selection/scan attempts for OWE BSS exceed the
configured threshold.

Explicitly set the PMF configuration to 0 (NO_MGMT_FRAME_PROTECTION) for
non-RSN associations. This specifically helps with OWE transition mode
when the network block is configured with PMF set to required, but the
BSS selected is in open mode. There is no point to try to enable PMF for
such an association.
This fixes issues with drivers that use the NL80211_ATTR_USE_MFP
attribute to set expectations for PMF use. The combination of non-RSN
connection with claimed requirement for PMF (NL80211_MFP_REQUIRED) could
cause such drivers to reject the connection in OWE transition mode.

If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for
all consecutive attempts as well. This did not allow recovery from state
mismatch between the ERP server and peer using full EAP authentication.
Address this by trying to use full (non-FILS) authentication when trying
to connect to an AP using the same ERP realm with FILS-enabled network
profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again
for the consecutive connections.

Timeout is increased by dfs_cac_ms from channel data, or by max CAC time
(10 minutes) if dfs_cac_ms is not defined. This is needed for some more
complex cases, e.g., when STA is acting as an active slave with DFS
offload enabled and decided to start CAC after receiving CONNECT
command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10
minutes).
Without such timeout modification wpa_supplicant will be unable to
connect to an AP on DFS channel, since the default authentication
timeout (10 s) is smaller than the minimum CAC time (60 s).
Tested with nl80211 DFS offload implementation.

Explicitly check the PMKSA cache entry to have matching SAE AKMP for the
case where determining whether to use PMKSA caching instead of new SAE

The RSN supplicant state machine PMK was set based on WPA PSK even for
the cases where SAE would be used. If the AP allows PMKSA caching to be
used with SAE, but does not indicate the selected PMKID explicitly in
EAPOL-Key msg 1/4, this could result in trying to use the PSK instead of
SAE PMK. Fix this by not setting the WPA-PSK as default PMK for SAE
network profiles and instead, configuring the PMK explicitly from the
found PMKSA cache entry.

When wpa_supplicant is running on a Linux interface that is configured in
promiscuous mode, and it is not a member of a bridge, incoming EAPOL
packets are processed regardless of the Destination Address in the frame.
As a consequence, there are situations where wpa_supplicant replies to
EAPOL packets that are not destined for it.
This behavior seems undesired (see IEEE Std 802.1X-2010, 11.4.a), and can
be avoided by attaching a BPF filter that lets the kernel discard packets
having pkt_type equal to PACKET_OTHERHOST.

Previously we set this flag to one in wpa_supplicant_init_iface() if
Wi-Fi controller does not have a dedicated P2P-interface.
This setting had effect only in scope of wpa_supplicant_init_iface() and
it contradicts with comment to struct wpa_interface::p2p_mgmt field.
This comment says that this flag is used only if Wi-Fi controller has
dedicated P2P-device interface.
Also it contradicts with usage of similiar p2p_mgmt field in struct
wpa_supplicant. Again struct wpa_supplicant::p2p_mgmt is set only for
dedicated P2P-device interface.

The special case of returning from wpa_supplicant_set_suites() when OWE
transition mode profile is used for an open association did not clear

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

The introduction of radio works and a delayed callback to complete
association/connection requests ended up breaking RSN pre-authentication
candidate list generation for the case of pre-connection scan results.
Previously, wpa_supplicant_associate() set the RSN state machine
configuration before returning and the calls to
wpa_supplicant_rsn_preauth_scan_results() immediately after this
function call were working fine. However, with the radio work callback,
the RSN state machine configuration started to happen only in that
callback which would be called soon after this code path has completed.
This resulted in the RSN state machine not knowing the selected SSID and
as such, rejecting all pre-authentication candidates.
Fix this by setting the RSN state machine configuration from
wpa_supplicant_associate() so that the existing callers of
wpa_supplicant_rsn_preauth_scan_results() can be used as-is to add
candidates for pre-authentication.
