====================
A few big new things:
* 802.11 frame encapsulation offload support
* more HE (802.11ax) support, including some for 6 GHz band
* powersave in hwsim, for better testing
Of course as usual there are various cleanups and small fixes.

Currently a mac80211 driver can only set the txq_limit when using
wake_tx_queue. Not all drivers use wake_tx_queue. This patch adds a new
element to wiphy allowing a driver to set a custom tx_queue_len and the
code that will apply it in case it is set. The current default is
1000 which is too low for ath11k when doing HE rates.

With multiple VIFS ath10k, and probably others, tries to find the
minimum txpower for all vifs and uses that when setting txpower in
the firmware.
If a second vif is added and starts to scan, it's txpower is not
initialized yet and it set to zero.
ath10k had a patch to ignore zero values, but then it is impossible
to actually set txpower to zero.
So, instead initialize the txpower to INT_MIN in mac80211, and let
drivers know that means the power has not been set and so should
be ignored.
This should fix regression in:

Before this patch, STA's would set new width of 160/80+80 MHz based on AP capability only.
This is wrong because STA may not support > 80MHz BW.
Fix is to verify STA has 160/80+80 MHz capability before increasing its width to > 80MHz.
The "support_80_80" and "support_160" setting is based on:
"Table 9-272 — Setting of the Supported Channel Width Set subfield and Extended NSS BW
Support subfield at a STA transmitting the VHT Capabilities Information field"

When using control port over nl80211 in AP mode with
pre-authentication, APs need to forward frames to other
APs defined by their MAC address. Before this patch,
pre-auth frames reaching user space over nl80211 control
port have no longer any information about the dest attached,
which can be used for forwarding to a controller or injecting
the frame back to a ethernet interface over a AF_PACKET
socket.
Analog problems exist, when forwarding pre-auth frames from
AP -> STA.
This patch therefore adds the NL80211_ATTR_DST_MAC and
NL80211_ATTR_SRC_MAC attributes to provide more context
information when forwarding.
The respective arguments are optional on tx and included on rx.
Therefore unaware existing software is not affected.
Software which wants to detect this feature, can do so
by checking against:

To support Pre Association Security Negotiation (PASN) while already
associated to one AP, allow user space to register to Rx
authentication frames, so that the user space logic would be able to
receive/handle authentication frames from a different AP as part of
PASN.
Note that it is expected that user space would intelligently register
for Rx authentication frames, i.e., only when PASN is used and
configure a match filter only for PASN authentication algorithm, as
otherwise the MLME functionality of mac80211 would be broken.
Additionally, since some versions of the user space daemons wrongly
register to all types of authentication frames (which might result in
unexpected behavior) allow such registration if the request is for a
specific authentication algorithm number.

In case of HE, the RX NSS is taken from the HE capabilities.
If the supported NSS capabilities that are reported by AP for
HE mode in the HE Capabilities element are different from the NSS
capabilities that are reported by AP for the VHT mode in the VHT
Capabilities element, use the lowest supported NSS to not get all
the values confused.

Check early on that a device has support for QoS (at least 4
queues) when it supports HT/VHT/HE, so we don't have to check
this while connecting.
This lets us clean up the code there: move some of it into
channel preparation to clean up a bit more, and then change
the logic to only check the "wmm_used" flag.
Additionally, disable HE consistently when VHT is disabled.

We only use the parsing CRC for checking if a beacon changed,
and elements with an ID > 63 cannot be represented in the
filter. Thus, like we did before with WMM and Cisco vendor
elements, just statically add these forgotten items to the
CRC:
- WLAN_EID_VHT_OPERATION
- WLAN_EID_OPMODE_NOTIF
I guess that in most cases when VHT/HE operation change, the HT
operation also changed, and so the change was picked up, but we
did notice that pure operating mode notification changes were
ignored.

It turns out that this wasn't a good idea, I hit a test failure in
hwsim due to this. That particular failure was easily worked around,
but it raised questions: if an AP needs to, for example, send action
frames to each connected station, the current limit is nowhere near
enough (especially if those stations are sleeping and the frames are
queued for a while.)
Shuffle around some bits to make more room for ack_frame_id to allow
up to 8192 queued up frames, that's enough for queueing 4 frames to
each connected station, even at the maximum of 2007 stations on a
single AP.
We take the bits from band (which currently only 2 but I leave 3 in
case we add another band) and from the hw_queue, which can only need
4 since it has a limit of 16 queues.

commit 08a5bdde38 ("mac80211: consider QoS Null frames for STA_NULLFUNC_ACKED")
Fixed a bug where we failed to take into account a
nullfunc frame can be either non-QoS or QoS. It turns out
there is at least one more bug in
ieee80211_sta_tx_notify(), introduced in
commit 7b6ddeaf27 ("mac80211: use QoS NDP for AP probing"),
where we forgot to check for the QoS variant and so
assumed the QoS nullfunc frame never went out
Fix this by adding a helper ieee80211_is_any_nullfunc()
which consolidates the check for non-QoS and QoS nullfunc
frames. Replace existing compound conditionals and add a
couple more missing checks for QoS variant.

TKIP replay protection was skipped for the very first frame received
after a new key is configured. While this is potentially needed to avoid
dropping a frame in some cases, this does leave a window for replay
attacks with group-addressed frames at the station side. Any earlier
frame sent by the AP using the same key would be accepted as a valid
frame and the internal RSC would then be updated to the TSC from that
frame. This would allow multiple previously transmitted group-addressed
frames to be replayed until the next valid new group-addressed frame
from the AP is received by the station.
Fix this by limiting the no-replay-protection exception to apply only
for the case where TSC=0, i.e., when this is for the very first frame
protected using the new key, and the local RSC had not been set to a
higher value when configuring the key (which may happen with GTK).

In case a radar event of CAC_FINISHED or RADAR_DETECTED
happens during another phy is during CAC we might need
to cancel that CAC.
If we got a radar in a channel that another phy is now
doing CAC on then the CAC should be canceled there.
If, for example, 2 phys doing CAC on the same channels,
or on comptable channels, once on of them will finish his
CAC the other might need to cancel his CAC, since it is no
longer relevant.
To fix that the commit adds an callback and implement it in
mac80211 to end CAC.
This commit also adds a call to said callback if after a radar
event we see the CAC is no longer relevant

This is a conversion case for the new function, keeping the flow of the
existing code as intact as possible. We also switch over to using
skb_mark_not_on_list instead of a null write to skb->next.
Finally, this code appeared to have a memory leak in the case where
header building fails before the last gso segment. In that case, the
remaining segments are not freed. So this commit also adds the proper
kfree_skb_list call for the remainder of the skbs.
