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.

Using BSS coloring is one way of improving performance on 802.11ax
radios, currently its only enabled by users adding he_bss_color to their
wireless UCI config.
This made sense as one could easily get BSS color collision as BSS color
range is 1-63.
Hostapd now has a way of dealing with BSS color collisions so we can just
assign a integer in the 1-63 range randomly if one is not set by users.

drv_mac80211_teardown fails silently if the device to be torn down is
not defined. This commit prints an error message.

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.

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.
