Currently, if ACS scan request fails, states are cleared and returned.
However, in case of MLO, there is a possibilty of getting return value
of -EBUSY. In this case, ACS can retry the scan request after some time
similary to the HT40 scan.
Hence, retry the scan after 5 seconds if -EBUSY is returned. Maximum of
15 re-attempts are made before giving up.

Currently, RADIUS client, auth server, and 802.1X are copied from the
first link's BSS into the non-first link during its setup. However,
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.

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.

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 4d3be9cdd1 ("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.

Signed-off-by: Jouni Malinen <quic_jouni@quicinc.com>
According to IEEE Std 802.11-2020, Operating classes Table E-2 (Europe)
and Table E-6 (China) map channels in the range 149 to 161 to the global
operating class 125, while Table E-1 (United States) maps these channels
to global operating classes 125 and 124 as well. The global operating
class 125 contains all channels from the global operating class 124 and
some additional channels.
Hence, to make the selection of the current operating class generic, use
operating class 125 for all 20 MHz channels in the range 149 to 161.

If a non-PSC 6 GHz channel with bandwidth higher than 20 MHz is
configured, duplicate beacons/FD/UBPR will be transmitted in other 20
MHz channels of the current configured bandwidth to aid in faster scan.
In such cases the duplicate FD needs to carry the Operating Class and
Primary Channel subfields for non-AP STAs to identify the primary
non-PSC.
IEEE Std 802.11-2020, 9.6.7.36 (FILS Discovery frame format):
"The Operating Class subfield specifies the operating class of the
Primary Channel of the transmitting AP (see 9.4.1.36).
The Primary Channel subfield is set to the channel number of the primary
channel (see 11.15.2) if the FILS Discovery frame is transmitted as a
non-HT duplicate PPDU; otherwise, the subfield is not present."
Hence, add the Operating Class and Primary Channel subfields if the
current channel is non-PSC and the channel bandwidth is 40 MHz or
higher.

AP operations are resumed with the same configuration.
