Currently, when the ACS is updating the puncturing bitmap, the function
acs_update_puncturing_bitmap() sets the primary channel bitmap to 0.
This leads to a potential issue where the primary channel could be
punctured if ACS selects a different best channel within the same
segment.
To fix this issue, ensure that the primary channel bitmap is correctly
set by calculating the index of the primary channel based on the

MLO: Swap Tx/Rx keys for GTK TKIP Michael MIC in MLO GTK KDE
While TKIP should not really be used at all anymore and is not allowed
for WPA3 (which is required for Wi-Fi 7), there are some deployed APs
that allow WPA2 PSK to be used with MLO and even allowing WPA+WPA2 mode
with TKIP as the group cipher). IEEE P802.11be/D5.0 does not seem to
explicitly disallow this combination, so handle the MLO GTK KDE key
processing similarly to the way GTK KDE is processed, i.e., including
swapping of Michael MIC Tx and Rx keys for TKIP.
This fixes issues with Michael MIC failures if TKIP is used as a group
cipher for a multi-link association.
Fix this by enabling HT by default if HE is enabled in the 2.4 GHz and 5
GHz bands. Similarly, enable VHT by default when HE is enabled in the 5
GHz band.
When the wiphy supports multiple bands and reports different capability
values between 5 GHz and 6 GHz channels, the 6 GHz mesh interface is
unable to correctly map the channel width in function
ibss_mesh_setup_freq(). This issue arises because the modes of 5 GHz and
6 GHz interfaces are the same (HOSTAPD_MODE_IEEE80211A) in supported
modes.
To address this, use function get_mode() to determine the appropriate
mode during mesh setup. This will iterates through all the hw_features
sets and ensures compatibility with the band of the channel supported in
hw_features set.
If SSID was not verified during the initial setup of an association, but
beacon protection was negotiated, try verify the SSID based on Beacon
frames that have been received after the first BIGTK has been
configured.
This is a variant of wpa_bss_get_ie() to allow IEs to be checked from
only Beacon frames similarly to how wpa_bss_get_vendor_ie_beacon()
behaves for vendor specific elements.
The new "bigtk_set=1" entry in the control interface STATUS command
output indicates that a BIGTK has been successfully configured. This
shows that beacon protection has been enabled for the current
association.
Indicate if SSID has been verified in STATUS output
Add a new "ssid_verified=1" entry into the control interface STATUS
command output if the SSID has been verified for the current
association. This verification may have been done implicitly (e.g., with
SAE H2E and FT protocol binding in the SSID into key derivation or with
FILS protecting the SSID element in the (Re)Association Request frame)
or explicitly with the recently added SSID protection mechanism during
the 4-way handshake.

there could be a case where the first link is not initialized fully
because of ACS/HT40 SCAN/DFS. Hence, in such cases, NULL is getting
copied and later it leads to segmentation fault.
Initialize those on behalf of the first link in such case and update it
so that the next time other non-first link can use it.
Add a new QCA vendor attribute to set interface offload type
Userspace tools can use QCA_WLAN_VENDOR_ATTR_CONFIG_IF_OFFLOAD_TYPE to
configure the different below acceleration features (hardware, software)
on a per interface basis.
0 - No acceleration Packets are processed through the Linux kernel
networking stack.
1 - Software based acceleration: Packets are processed through the
shortcut forwarding engine (SFE) to bypass the Linux networking stack
for improved throughput performance. This option is applicable for AP,
STA, and Mesh mode and available for all radio designs. From the
performance aspect, this option consumes more CPU compared to the other
two options. Linux traffic control can be further applied with this
option to have more control on the traffic flows.
2 - Hybrid acceleration (software and hardware acceleration combined):
Packets are processed through both hardware and software in this case.
Packet classification is done by the hardware and then the packets are
delivered to software along with classification results as meta data.
Software can choose to do more classification/QoS based on use cases.
This is applicable for AP, STA, and Mesh modes and is available for all
radio designs. From the performance aspect, this option consumes
relatively less CPU compared to the SFE option above. Linux traffic
control rules cannot be applied with this option.
3 - Hardware based acceleration : Packets are processed through special
hardware (Direct Switch) rings which can directly forward the packets
between ethernet hardware and Wi-Fi hardware with very less software
involvement. This is applicable only for AP and STA modes; not
applicable for Mesh mode. From the performance aspect, this option
consumes very much less CPU compared to the other options. Linux traffic
control rules cannot be applied when this option is used. This option is
applicable only for specific radio designs. When this option is not
available, the default option (SFE) would be configured.

WNM: Group rekeying skipping with BSS max idle period management
Allow hostapd to be configured to not disconnect a STA if the STA fails
to reply to a group key handshake when BSS max idle period management is
used. This might be needed for some STAs that use aggressive power
saving (e.g., battery powered IoT devices).
This is disabled by default since this can delayed group rekeying
slightly and also to maintain the previous behavior. The more relaxed
operation can be enabled with the new configuration parameter
no_disconnect_on_group_keyerror=1.

P2P: Fix fast IP address allocation for invitation of a persistent group
Allocate static IPv4 address in EAPOL frames during 4-way handshake
instead of DHCP when using P2P invitation. wpa_s->current_bss needs to
be set for the P2P specific IP address assignment mechanism to be used
in wpa_supplicant_rsn_supp_set_config(). This worked for the initial P2P
connection, but not for some cases reinvoking a persistent group.
Since there is only one AP (P2P GO) in the P2P client case, the
conditions added in commit 4d3be9cdd143 ("Postpone updating of
wpa_s->current_bss till association event") are not needed and the
easiest approach for this is to allow current_bss to be set for
p2p_in_invitation cases. If the GO P2P Interface Address (BSSID) could
be determined for all the related cases, this could be addressed a bit
more cleanly by setting the go_bssid argument for
wpas_start_p2p_client(), but that can be left as a possible future step.
