Since wpa_supplicant version 2.10 the extended capabilities MSCS and SCS
are advertised in the (Re)Association Request frames.
This causes the association request to be rejected by several access
points. Issue was observed with:
- D-Link DIR600
- TP-Link AC1900
- Synology MR2200ac
To avoid this issue the extended capabilities MSCS and SCS shall only be
added if the bss also supports them. While this may not follow the exact
behavior described in IEEE 802.11, this is a reasonable compromise to
avoid interoperability issues since these capabilities cannot be used
with an AP that does not support them anyway.
Note: The Extended Capabilities element is only included in the
Association Request frames if the AP also sent its extended capabilities
(see wpas_populate_assoc_ies()) as a workaround for misbehaving APs.
This workaround exists since version 2.1.

There is a delay between sending Association Response frame after having
received Association Request frame, due to the fact that between
receiving the request and sending the response the Beacon frame contents
is updated, after analyzing inputs from the STA. There may be several
updates if multiple fields need to change. This can cause issues with
some devices in noisy environments with many BSSs and connected STAs.
Optimize this by updating the beacon only once, even if there are
multiple reasons for updates.

If the number of TBTT info is greater than RNR_TBTT_INFO_COUNT_MAX, the
new Neighbor AP Information field would need to be added in the RNR
element. However, the condition of adding Neighbor AP Information field
does not consider number of TBTT info. That would cause invalid Neighbor
AP Information field (the while loop will fill data by eid pointer) when

When it comes to set some BSS's beacon, there are two reasons to
update the beacon of co-located hostapd_iface(s) at the same time:
1. 6 GHz out-of-band discovery
2. MLD operational parameters update
BSS load update is unrelated with the above two reasons, and therefore
is not the case to update beacon for co-location. Moreover, updating
beacon for co-location when BSS load update makes hostapd set beacon too
frequently, which makes hostapd busy setting beacon in a multi-BSS case.
Add a new function to update beacon only for current BSS and use the
function during BSS load update.

Drivers will often report regdom changes in the middle of a scan if they
detect during that scan that the regulatory domain has changed. If this
happens and we enter a regdom that supports 6 GHz channels when the
previous one didn't (this often happens in 6 GHz-capable regdoms for
devices after suspend/resume), immediately trigger a 6 GHz-only scan if
we were not able to connect to an AP on a legacy band.
This should significantly improve connection time to 6 GHz AP after
regdom has been reset.

After GO negotiation is completed, the P2P Client needs to scan the GO
before connecting. Only SSID was specified for this and the driver still
might need to scan all channels which wastes time. wpa_supplicant can
pass the known BSSID in the scan request in additional P2P cases and
this allows the driver sto stop the scan once the specific BSSID is
found. This helps reduce some time for P2P connection.

A driver may not support setting MAC address when interface is UP, so
wpa_supplicant used to always sets the interface down for MAC address

Certain internet service providers transmit VLAN 0 priority tagged
EAPOL frames from the ONT towards the residential gateway. VID 0
should be ignored, and the frame processed according to the priority
set in the 802.1P bits and the encapsulated EtherType (i.e., EAPOL).
The pcap filter utilized by l2_packet_* is inadquate for this use case.
Here we modify the pcap filter on FreeBSD to accept both unencapsulated
and encapsulated (with VLAN 0) EAPOL EtherTypes. This preserves the
original filter behavior while also matching on encapsulated EAPOL.
Additional work is required to support this handling on other platforms.
We also modify the rx_receive handler to offset the packet buffer
and length when handling dot1q encapsulated frames so the existing
packet parsing code works as-is.
