The network block bssid parameter can be used to force a specific BSS to
be used for a connection. It is also possible to modify this parameter
during an association. Previously, that did not result in any
notification to the driver which was somewhat problematic with drivers
that take care of BSS selection. Add a new mechanism to allow
wpa_supplicant to provide a driver update if the bssid parameter change
for the current connection modifies roaming policy (roaming
allowed/disallowed within ESS).

An interoperability issue with a deployed AP has been identified where
the connection fails due to that AP failing to operate correctly if
PMKID is included in the Association Request frame. To work around this,
allow EAPOL-Start packet to be transmitted on startWhen reaching 0 even
when trying to use PMKSA caching. In practice, this allows fallback to
full EAP authentication if the AP/Authenticator takes more than 1-2
seconds to initiate 4-way handshake for PMKSA caching or full EAP
authentication if there was no PMKSA cache match.

Previously, the shorter startWhen value was used based on build
parameters (i.e., if WPS was enabled). This is not really ideal and the
knowledge of WPS use can be provided to the EAPOL state machine to allow
this (and similar WPS workarounds) to be done only when the association
is for the purpose of WPS.
Reduce the default startWhen value from 3 to 2 seconds for non-WPS case
since WPS builds have likely received most testing for the past years
with the 1 second value and there is no strong justification for forcing
the longer 3 second wait should a frame be lost or something else
require the EAPOL-Start to initiate operation after a connection.

Currently to signal PropertiesChanged upon group client
removal (group property), wpa_supplicant dbus uses wpa_s
members like go_dev_addr and current_ssid, for instance.
Thus, deferring p2p client deauth to after dbus notify,
but keeping the same order as before, solves the issue,
as wpa_s is not yet completely deinitialized.

"Age" is the age in seconds since the BSS was last seen, and is
emitted as a PropertyChanged signal whenever the BSS is updated
from a scan result. It also returns the correct age when queried
directly.
This property can be used to resolve issues where, if no other
properties of the BSS changed from scan results (for example,
if the BSS always had 100% signal) no D-Bus signals would be
emitted to indicate that the BSS had just been seen in the scan.

Some deployed APs send two credentials when in mixed-WPA/WPA2
configuration; one for the WPA-Personal/TKIP and the other for
WPA2-Personal/CCMP. Previously, this would result in two network blocks
getting added for the single AP. This can be somewhat confusing and
unnecessary, so merge such credentials into a single one that allows
both WPA and WPA2 to be used.

Previously, the P2P Interface Address of the peer gets updated in the
peer table every time based on the scan results.
For example, in a two port concurrency scenario, where the peer device
has two interfaces with unique P2P Interface Addresses and with same P2P
Device Address, based on the Probe Response/Beacon frames from these two
interfaces, their peer table gets updated, but each of these updates
happens in the peer table only based on the P2P Device Address. So, the
same peer's P2P Interface address is updated every time and hence, at
any instant, only one P2P Device Address to P2P Interface Address
mapping entry exist in the peer table for the peer which has two
interfaces.
When we try to join a group operated by the peer, lookup happens in the
peer table and when an interface entry is not available, the pending
interface address gets overwritten with the P2P Device Address and hence
the P2P connection can fail. Since the BSS table is the one that is
up-to-date, this fix will ensure that the interface overwriting will
happen only when there is no BSS entry for the pending P2P Interface
Address as well.

VENDOR_ELEM_GET <frame id>
VENDOR_ELEM_REMOVE <frame id> <hexdump of elem(s)>
VENDOR_ELEM_REMOVE <frame id> *
The following frames are supported in this commit (additional frames can
be added in the future):
0 = Probe Request frame in P2P device discovery
1 = Probe Response frame from P2P Device role
2 = Probe Response frame from P2P GO
3 = Beacon frame from P2P GO
4 = PD Req
5 = PD Resp
6 = GO Neg Req
7 = GO Neg Resp
8 = GO Neg Conf
9 = Invitation Request
10 = Invitation Response
11 = P2P Association Request
12 = P2P Association Response
One or more vendor element can be added/removed with the commands. The
hexdump of the element(s) needs to contain the full element (id, len,
payload) and the buffer needs to pass IE parsing requirements to be
accepted.

Previously, offloaded scanning (PNO) on Android was including SSIDs from
all enabled networks regardless of the scan_ssid parameter which
resulted in different behavior for the offloaded case when comparing to
wpa_supplicant initiated scans.
Use the sched_scan match filter to allow broadcast SSID to be used for
scan_ssid=1 networks also with PNO to avoid running active scans for
SSIDs that have not been explicitly marked as requiring an SSID-specific
scan. This reduces exposure of configured network names on the device
when running offloaded scans while the host device is in sleep.

The new "scan_id=<comma separated list of network ids>" parameter can
now be used to specify a list of network ids that have scan_ssid=1 to
indicate active scanning of the SSID. This adds the listed SSIDs to the
scan command to allow manual scan requests to perform active scans for
hidden SSIDs. For example, "SCAN scan_id=1,7,11" would run a scan with
the SSID fetched from the configured network blocks 1, 7, and 11
(assuming those are set with scan_ssid=1). The SSIDs will be included
even from network blocks that are currently disabled.
The maximum number of SSIDs added to the request is limited by the
driver support. If more than supported values are specified, the command
will fail (returns "FAIL").
