c41d0840a1 nl80211: Allow driver-based roam to change ESS
This extends NL80211_CMD_ROAM event processing to allow the driver to
roam to another ESS (different SSID) when using offloaded BSS selection.

ad4430971f Add Extended Capabilities element to all Probe Request frames
Always add the Extended Capabilities element to Probe Request frames (in
case it is not all zeros) to publish support for driver advertised
capabilities and wpa_supplicant specific capabilities.

This also fixes the case where Extended Capabilities element was added
for Interworking cases, but did not use the driver advertised ones and
did not handle other capabilities supported by wpa_supplicant.

9bd566a33a Delay AP selection if all networks are temporarily disabled
If all networks are temporarily disabled, delay AP selection until at
least one network is enabled. Running AP selection when all networks are
disabled is useless as wpa_supplicant will not try to connect. In
addition, it will result in needless scan iterations that may delay the
connection when it is needed.

701f3961e3 Don't optimize scan frequencies if selected network has changed
When disconnecting from a BSS, the next scan is optimized to scan only
the channels used by the connected ESS. But when disconnecting because a
new network was selected, this optimization is wrong because
wpa_supplicant is now trying to connect to another ESS. Fix this by not
optimizing the scan frequencies in case the selected network has
changed.

Interworking automatic network selection does not get triggered because

is only triggered when AQNP fetch cycle, that is, ANQP exchange with

41312fc7ef mesh: Leave mesh in driver setup if initialization fails

a51c40aa35 P2P: Fix regression in start-GO/AP through a "fake" scan
Commit 3f9ebc439c ('P2P: Allow AP/GO
interface to be started while P2P-in-progress') moved the
wpa_s->connect_without_scan and wpa_s->last_scan_req checks to an
earlier place within the wpa_supplicant_scan() function without
adjusting wpa_s->last_scan_req. This variable was set between the old
and new location, so the new location needs to use wpa_s->scan_req.

This fixes an issue where AP/GO operations were not properly started in
some operation sequence. Instead, a station mode scan was executed. This
issue could be triggered, e.g., by running the no_go_freq test case
followed by autogo_random_channel.

0d2030ee20 Use estimated throughput to improve roaming selection
Previously, within-ESS roaming was skipped if the selected BSS did not
have a higher signal strength than the current BSS regardless of AP
capabilities. This could result in not moving to a BSS that would
provide higher throughput, e.g., due to larger channel bandwidth or
higher rates (HT/VHT MCS).

Use estimated throughput information from scan result processing to
allow within-ESS roaming if the selected BSS is likely to provide better
throughput even if the current BSS has larger RSSI.

a1b790eb9d Select AP based on estimated maximum throughput
This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as
a criteria for sorting the results. This extends the earlier design by
taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.

In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not
low enough to prevent higher MCS use.

71d77adb6d Update current BSS level when signal change event occurs
When an EVENT_SIGNAL_CHANGE occurs the bgscan is informed about this
change but the new RSSI value is not stored. In consequence, when
roaming candidates are evaluated, the RSSI value of the current BSS used
to compare is an old one obtained during the last scan rather than the
new one given by the signal change event. This leads sometimes to bad
decision when selecting a new BSS for roaming.

This patch solves the issue by updating the current BSS level when
receiving a signal change event in order to have a very up-to-date
current signal value when choosing an new BSS.
