SM Power Save was described in somewhat unclear manner in IEEE Std
802.11n-2009 as far the use of it locally in an AP to save power. That
was clarified in IEEE Std 802.11-2016 to allow only a non-AP STA to use
SMPS while the AP is required to support an associated STA doing so. The
AP itself cannot use SMPS locally and the HT Capability advertisement
for this is not appropriate.
Remove the parts of SMPS support that involve the AP using it locally.
In practice, this reverts the following commits:
04ee647d58 ("HT: Let the driver advertise its supported SMPS modes for AP mode")
8f461b50cf ("HT: Pass the smps_mode in AP parameters")

A driver supports FT if it either supports SME or the
NL80211_CMD_UPDATE_FT_IES command. When selecting AKM suites,
wpa_supplicant currently doesn't take into account whether or not either
of those conditions are met. This can cause association failures, e.g.,
when an AP supports both WPA-EAP and FT-EAP but the driver doesn't
support FT (wpa_supplicant will decide to do FT-EAP since it is unaware
the driver doesn't support it). This change allows an FT suite to be
selected only when the driver also supports FT.

The internal WMM AC parameters use just the exponent of the CW value,
while nl80211 reports the full CW value. This led to completely bogus
CWmin/CWmax values in the WMM IE when a regulatory limit was present.
Fix this by converting the value to the exponent before passing it on.

Linux kernel v4.17 added the ability to request sending controlled port
frames (e.g., IEEE 802.1X controlled port EAPOL frames) via nl80211
instead of a normal network socket. Doing this provides the device
driver with ordering information between the control port frames and the
installation of keys. This empowers it to avoid race conditions between,
for example, PTK replacement and the sending of frame 4 of the 4-way
rekeying handshake in an RSNA. The key difference between the specific
control port and normal socket send is that the device driver will
certainly get any EAPOL frames comprising a 4-way handshake before it
gets the key installation call for the derived key. By flushing its TX
buffers it can then ensure that no pending EAPOL frames are
inadvertently encrypted with a key that the peer will not yet have
installed.
Add a CONTROL_PORT flag to the hostap driver API to report driver
capability for using a separate control port for EAPOL frames. This
operation is exactly like an Ethernet send except for the extra ordering
information it provides for device drivers. The nl80211 driver is
updated to support this operation when the device reports support for
NL80211_EXT_FEATURE_CONTROL_PORT_OVER_NL80211. Also add a driver op
tx_control_port() for request a frame to be sent over the controlled
port.

It was possible for the driver to advertise support for channels that
are not found from wpa_supplicant frequency-to-channel mapping (e.g.,
channel 182 at 5910 MHz) and that resulted in not initializing the
channel number information. Fix this by explicitly clearing the full
struct hostapd_channel_data buffer before parsing the information into
it from the driver.
This avoids some conditional jumps that could have dependent on
uninitialized values.

SUITE_B_192 AKM capability was indicated for all devices using the
nl80211 driver (without the QCA vendor specific AKM capability
indication). However, some devices can't handle Suite B 192 due to
insufficient ciphers supported. Add a check for CCMP-256 or GCMP-256
cipher support and only indicate SUITE_B_192 capability when such cipher
is supported. This allows compiling with CONFIG_SUITEB192 and still get
proper response to the 'GET_CAPABILITY key_mgmt' command. Under Android
it can also serve as a dynamic way for HAL to query platform for

IEEE P802.11ay defines Enhanced Directional Multi-Gigabit (EDMG) STA and
AP which allow channel bonding of 2 channels and more.
nl80211 provides the driver's EDMG capabilities from the kernel
using two new attributes:
NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16
GHz channel(s) that are supported by the driver.
NL80211_BAND_ATTR_EDMG_BW_CONFIG - represents the channel bandwidth
configurations supported by the driver.
The driver's EDMG capabilities are stored inside struct hostapd_hw_modes.
As part of the connect request and starting AP, EDMG parameters are
passed as part of struct hostapd_freq_params.
The EDMG parameters are sent to the kernel by using two new attributes:
NL80211_ATTR_WIPHY_EDMG_CHANNEL and NL80211_ATTR_WIPHY_EDMG_BW_CONFIG
which specify channel and bandwidth configuration for the driver to use.
This implementation is limited to CB2 (channel bonding of 2 channels)
and the bonded channels must be adjacent.

The HE capabilities are no longer per PHY but per iftype on this
specific PHY. It is therefore no longer enough to just parse the AP
capabilities.
The he_capabilities are now duplicated to store all information for
IEEE80211_MODE_* which hostap cares about. The nl80211 driver fills in
this information when the iftype supports HE. The rest of the code still
only uses the IEEE80211_HE_AP portion but can be extended later to also
use other HE capabilities.

ETSI EN 301 893 v2.1.1 (2017-05) standard defines a new channel access
mechanism that all devices (WLAN and LAA) need to comply with.
In previous versions the device was allowed by ETSI to implement
802.11 channel access mechanism based on a set of priority classes
which are taken from 802.11. According of the new standard there
might be some exceptions which require ETSI countries to follow
more restrictive rules. In such a case the AP's wmm IE need to
comply with ETSI limitation. To be able to do so the regulatory
domain passes the new limitation values if needed.
Implement this, by storing it and use it to calculate the new
WMM parameters.
This commit adds determination of regulator limitations to
NL80211_CMD_GET_WIPHY processing so that the information is available
for upper layer implementation to use later when constructing WMM
element.

The places using drv->use_monitor were already skipping creation of the
monitor interface if drv->device_ap_sme == 0. This means that the

to set drv->use_monitor to zero for all such cases. This fixes an issue
with management frame subscription not happening properly for the case
where the AP SME is in the driver and the driver supports monitor
