122cdd5925 Enable TWT responder AP role only if IEEE 802.11ax/HE is enabled
Set TWT responder configurator in the driver parameters only when the AP
is configured with HE enabled. This was already done for the extended
capability bit generation in commit 8de0ff0fa1 ("HE: Add TWT responder
extended capabilities field"), but this parameter for the driver command
to start the AP in _ieee802_11_set_beacon() missed the condition.

Move the ieee80211ax check into the common helper function to cover both
cases. In addition, add a check for disable_11ax to cover the case where
HE is disabled for a specific BSS.

96a604128b Use separate PASN capabilities for AP and STA modes
Use separate capabilities for AP and STA modes for P802.11az security

and protection of range negotiation and measurement management frames

P802.11az security parameters are considered to be supported for both
station and AP modes if the driver sets NL80211_EXT_FEATURE_SECURE_LTF,
NL80211_EXT_FEATURE_SECURE_RTT, and
NL80211_EXT_FEATURE_PROT_RANGE_NEGO_AND_MEASURE flags. The driver can
advertize capabilities specific to each mode using
QCA_WLAN_VENDOR_FEATURE_SECURE_LTF*,
QCA_WLAN_VENDOR_FEATURE_SECURE_RTT*, and
QCA_WLAN_VENDOR_FEATURE_PROT_RANGE_NEGO_AND_MEASURE* flags.

bafe35df03 Move CHANWIDTH_* definitions from ieee80211_defs.h to defs.h
Move most of CHANWIDTH_* definitions from ieee80211_defs.h to defs.h as
the definitions are getting used mostly for internal purpose only. Also
change prefix of the definitions to CONF_OPER_CHWIDTH_* and update in
all the files accordingly.

Leave the couple of VHT-specific exceptions to use the old defines (the
reason why they were originally added as VHT values), to avoid use of
clearly marked configuration values in information elements. In
addition, use the defines instead of magic values where appropriate.

e059d8ece8 Update the Extended Capability element to struct sta_info
Only the SME-in-hostapd case updated sta->ext_capability while the
SME-in-the-driver case updated sta->qos_map_enabled, but not other items

a826ff2d95 Ignore group-addressed SA Query frames
These frames are used for verifying that a specific SA and protected
link is in functional state between two devices. The IEEE 802.11
standard defines only a case that uses individual MAC address as the
destination. While there is no explicit rule on the receiver to ignore
other cases, it seems safer to make sure group-addressed frames do not
end up resulting in undesired behavior. As such, drop such frames
instead of interpreting them as valid SA Query Request/Response.

f9da7505bf OCV: Include and verify OCI in SA Query frames
Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.

On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.

Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.

As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

d514b50265 WNM: Collocated Interference Reporting
Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.

For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".

For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).
