f338f76a66 mac80211: parse the correct set of HE capabilities for AP mode
It is common for 802.11ax NICs to support more than just AP mode, which
results in there being a distinct set of HE capabilities for each mode. As
(bad) luck would have it, iw prints out info for each HE mode in sequential
order according to `enum nl80211_iftype`, and AP mode isn't always first.

As a result, the wrong set of HE capabilities can be parsed if an AP NIC
supports station (managed) mode or any other mode preceding AP mode, since
only the first set of HE capabilities printed by iw is parsed from awk's
output.

This has a noticeable impact on beamforming for example, since managed mode
usually doesn't have beamformer capabilities enabled, while AP mode does.
Hostapd won't be set up with the configs to enable beamformer capabilities
in this scenario, causing hostapd to disable beamforming to HE stations
even when it's supported by the AP.

Always parse the correct set of HE capabilities for AP mode to fix this.
This is achieved by trimming all of iw's output prior to the AP mode
capabilities, which ensures that the first set of HE capabilities are
always for AP mode.

d2d5aabdbb hostapd: introduce min_tx_power option
Introduce a new option min_tx_power to configure the minimum permitted
max TX power (in dBm) for ACS and DFS channel selection.

Imagine the following regulatory rules:
  * 5180 MHz [36] (21.0 dBm)
  * 5200 MHz [40] (21.0 dBm)
  * 5220 MHz [44] (21.0 dBm)
  * 5240 MHz [48] (21.0 dBm)
  * 5260 MHz [52] (20.0 dBm) (radar detection)
  * 5280 MHz [56] (20.0 dBm) (radar detection)
  * 5300 MHz [60] (20.0 dBm) (radar detection)

  * 5500 MHz [100] (21.0 dBm) (radar detection)
  * 5520 MHz [104] (21.0 dBm) (radar detection)
  * 5540 MHz [108] (21.0 dBm) (radar detection)
  * 5560 MHz [112] (21.0 dBm) (radar detection)
  * 5580 MHz [116] (21.0 dBm) (radar detection)
  * 5600 MHz [120] (21.0 dBm) (radar detection)

  * 5700 MHz [140] (21.0 dBm) (radar detection)
  * 5720 MHz [144] (13.0 dBm) (radar detection)
  * 5745 MHz [149] (13.0 dBm)
  * 5765 MHz [153] (13.0 dBm)
  * 5785 MHz [157] (13.0 dBm)
  * 5805 MHz [161] (13.0 dBm)
  * 5825 MHz [165] (13.0 dBm)
  * 5845 MHz [169] (13.0 dBm)
  * 5865 MHz [173] (13.0 dBm)

When ACS or DFS end up selecting channel 144 or higher, some clients
might no longer be able to communicate with the AP due to the TX power
being limited to 13 dBm. Setting min_tx_power to 20 will result in
hostapd not considering these channels during ACS or after a DFS event.

f2982bcc89 hostapd: introduce background_radar option
Introduce a new option background_radar to toggle hostapd's background
radar feature. Enabling this allows DFS CAC to run on dedicated radio RF
chains while the radio(s) are otherwise running normal AP activities on
other channels.

As OpenWrt configures hostapd to use a channel list even when a single
channel is configured, using this feature requires a list of channels in
/etc/config/wireless. Alternatively, channel can be set to auto.

d515f6b6cd mac80211: always call wireless_set_data (FS#3784)
When wifi is turned off, drv_mac80211_teardown sometimes fails (silently)
because the device to be torn down is not defined.

This situation arises if drv_mac80211_setup was called twice when
wifi was turned on.

This commit ensures that the device to be torn down is always defined
in drv_mac80211_teardown.

Steps to reproduce:

1) Use /sbin/wifi to turn on wifi.
   uci set wireless.@wifi-iface[0].disabled=0
   uci set wireless.@wifi-device[0].disabled=0
   uci commit
   wifi

2) Use /sbin/wifi to turn off wifi.
   uci set wireless.@wifi-device[0].disabled=1
   uci commit
   wifi

3) Observe that wifi is still up.

a29ab3b79a mac80211: fix no_reload logic (FS#3902)
If drv_mac80211_setup is called twice with the same wifi configuration,
then the second call returns early with error HOSTAPD_START_FAILED.
(wifi works nevertheless, despite the fact that setup is incomplete.  But
"ubus call network.wireless status" erroneously reports that radio0 is down.)

The relevant part of drv_mac80211_setup is,

if [ "$no_reload" != "0" ]; then
        add_ap=1
        ubus wait_for hostapd
        local hostapd_res="$(ubus call hostapd config_add "{\"iface\":\"$primary_ap\", \"config\":\"${hostapd_conf_file}\"}")"
        ret="$?"
        [ "$ret" != 0 -o -z "$hostapd_res" ] && {
                wireless_setup_failed HOSTAPD_START_FAILED
                return
        }
        wireless_add_process "$(jsonfilter -s "$hostapd_res" -l 1 -e @.pid)" "/usr/sbin/hostapd" 1 1
fi

This commit sets no_reload = 0 during the second call of drv_mac80211_setup.

It is perhaps worth providing a way to reproduce the situation
where drv_mac80211_setup is called twice.

When /sbin/wifi is used to turn on wifi,
   uci set wireless.@wifi-iface[0].disabled=0
   uci set wireless.@wifi-device[0].disabled=0
   uci commit
   wifi

/sbin/wifi makes the following ubus calls,
   ubus call network reload
   ubus call network.wireless down
   ubus call network.wireless up

The first and third ubus calls both call drv_mac80211_setup,
while the second ubus call triggers wireless_device_setup_cancel.
So the call sequence becomes,

   drv_mac80211_setup
   wireless_device_setup_cancel
   drv_mac80211_setup

In contrast, when LuCI is used to turn on wifi only a single call
is made to drv_mac80211_setup.
