dda5d9e315 nl80211: Add support for EDMG channels
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.

29d8bd1dec nl80211: Add driver multi iftype HE capability parsing
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.

636c02c6e9 nl80211: Add regulatory wmm_limit to hostapd_channel_data
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.

1b90aae929 nl80211: Remove QCA vendor specific HE capability handling
The QCA_NL80211_VENDOR_SUBCMD_GET_HE_CAPABILITIES attributes are not
up-to-date with the latest P802.11ax/D4.0 capabilities and would need to
be updated or replaced. Since the variables from this functionality were
not used for anything in practice, it is easier to simply remove this
functionality completely to avoid issues with upcoming updates to use
upstream nl80211 information to determine HE capabilities.

This is practically reverting the commit ca1ab9db2a ("hostapd: Get
vendor HE capabilities").

660103eca9 nl80211: Use the monitor interface only without device_ap_sme support
The places using drv->use_monitor were already skipping creation of the
monitor interface if drv->device_ap_sme == 0. This means that the
monitor interface operations would not have worked anyway and it is safe
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
interfaces (for other purposes).

This commit also removes the check for monitor support and the
previously used workaround that cleared drv->use_monitor in
drv->device_ap_sme == 1 case if monitor interface was not supported
since that condition cannot occur anymore.

0e92fb8fae rfkill: Match only the correct expected wiphy rfkill
On systems that have multiple WLAN rfkill instances, the rfkill code
can become confused into thinking that the device was unblocked when
in fact it wasn't, because it only matches on the WLAN type.

Since it then stores the new (unblocked) state from the wrong rfkill
instance, it will never retry the failing IFF_UP operation and the
user has to toggle rfkill again, or otherwise intervene manually, in
this case to get back to operational state.

Fix this by using the existing (but unused) ifname argument when the
rfkill instance is created to match to a specific rfkill index only.

As a P2P Device interface does not have a netdev interface associated
with it, use the name of a sibling interface to initialize the rfkill
context for the P2P Device interface. For nl80211, as the wiphy index
is known only after getting the driver capabilities from the kernel,
move the initialization of the rfkill object to
wpa_driver_nl80211_finish_drv_init().
