drv_mac80211_teardown fails silently if the device to be torn down is

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.

From the patch series description:
Several security issues in the 802.11 implementations were found by
Mathy Vanhoef (New York University Abu Dhabi), who has published all
the details at
https://papers.mathyvanhoef.com/usenix2021.pdf
Specifically, the following CVEs were assigned:
* CVE-2020-24586 - Fragmentation cache not cleared on reconnection
* CVE-2020-24587 - Reassembling fragments encrypted under different
keys
* CVE-2020-24588 - Accepting non-SPP A-MSDU frames, which leads to
payload being parsed as an L2 frame under an
A-MSDU bit toggling attack
* CVE-2020-26139 - Forwarding EAPOL from unauthenticated sender
* CVE-2020-26140 - Accepting plaintext data frames in protected
networks
* CVE-2020-26141 - Not verifying TKIP MIC of fragmented frames
* CVE-2020-26142 - Processing fragmented frames as full frames
* CVE-2020-26143 - Accepting fragmented plaintext frames in
protected networks
* CVE-2020-26144 - Always accepting unencrypted A-MSDU frames that
start with RFC1042 header with EAPOL ethertype
* CVE-2020-26145 - Accepting plaintext broadcast fragments as full
frames
* CVE-2020-26146 - Reassembling encrypted fragments with non-consecutive
packet numbers
* CVE-2020-26147 - Reassembling mixed encrypted/plaintext fragments
In general, the scope of these attacks is that they may allow an
attacker to
* inject L2 frames that they can more or less control (depending on the
vulnerability and attack method) into an otherwise protected network;
* exfiltrate (some) network data under certain conditions, this is
specific to the fragmentation issues.
A subset of these issues is known to apply to the Linux IEEE 802.11
implementation (mac80211). Where it is affected, the attached patches
fix the issues, even if not all of them reference the exact CVE IDs.
In addition, driver and/or firmware updates may be necessary, as well
as potentially more fixes to mac80211, depending on how drivers are
using it.
Specifically, for Intel devices, firmware needs to be updated to the
most recently released versions (which was done without any reference
to the security issues) to address some of the vulnerabilities.
To have a single set of patches, I'm also including patches for the
ath10k and ath11k drivers here.
We currently don't have information about how other drivers are, if
at all, affected.

When transmitting to a receiver in dynamic SMPS mode, all transmissions that
use multiple spatial streams need to be sent using CTS-to-self or RTS/CTS to
give the receiver's extra chains some time to wake up.
This fixes the tx rate getting stuck at <= MCS7 for some clients, especially
Intel ones, which make aggressive use of SMPS.

802.11w feature is always enabled in the build time.
It doesn't make sense to opt-in 802.11w per driver as hostapd will always
be compiled with this feature enabled.
As suggested by Hauke Mehrtens, for now keep 11w enabled in build_features.h
for compatibility reasons. This option will be dropped when LuCI is adjusted.

Testing with hwsim reveals two problems:

returning the last one when asked for more;
2. The base address has the local bit set and the operation unsets it.

The vendor driver does things differently based on what it finds in the
SoC's CHIP_VER register, which should tell whether this is MT7620N or
MT7620A (PKG) and probably also the revision (VER) and most likely
also something about the silicon implementer (ECO).
Introduce codepaths just like the ones in the vendor driver to handle
the different chips properly.
Some of those paths are most likely dead code and left-overs from FPGA
versions or early prototypes of the chip. It'd thus be great if people
can post their kernel logs, at least the line telling the chip version
and eco, so we know what's actually out there in the wild -- all I
could find is
[ 0.000000] SoC Type: Ralink MT7620A ver:2 eco:6
and
[ 0.000000] SoC Type: Ralink MT7620N ver:2 eco:6
which would make things easier, as then we really just need to know
whether it's MT7620N or MT7620A and not care about FPGA or prototypes
with ver <= 1 and eco <= 2.
