19b815ed71 wifi: mac80211: chanctx emulation set CHANGE_CHANNEL when in_reconfig 
Chanctx emulation didn't info IEEE80211_CONF_CHANGE_CHANNEL to drivers
during ieee80211_restart_hw (ieee80211_emulate_add_chanctx). It caused
non-chanctx drivers to not stand on the correct channel after recovery.
RX then behaved abnormally. Finally, disconnection/reconnection occurred.

So, set IEEE80211_CONF_CHANGE_CHANNEL when in_reconfig.

b5d14b0c67 wifi: virt_wifi: avoid reporting connection success with wrong SSID 
When user issues a connection with a different SSID than the one
virt_wifi has advertised, the __cfg80211_connect_result() will
trigger the warning: WARN_ON(bss_not_found).

The issue is because the connection code in virt_wifi does not
check the SSID from user space (it only checks the BSSID), and
virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS
even if the SSID is different from the one virt_wifi has advertised.
Eventually cfg80211 won't be able to find the cfg80211_bss and generate
the warning.

Fixed it by checking the SSID (from user space) in the connection code.

1a3364e963 wifi: iwlwifi: keep BHs disabled when TXing from reclaim 
During reclaim, we may release the txq->lock spinlock in order to call
iwl_trans_tx to queue new frames. The iwl_trans_tx function expects to
be called with BHs disabled and iwl_pcie_reclaim is most of the times
called with BHs disabled already. However, reclaim can also happen after
flushing a STA and in that case BHs will not be disabled.

Solve this corner case by only releasing the spinlock but keeping BHs
disabled.

We have some new features in ath12k along with some cleanups in ath11k
and ath12k. Also notable are some device-tree changes to allow certain
ath11k and ath12k devices to work with a new power sequencing
subsystem.

Major changes:

ath12k

* DebugFS support for datapath statistics
* WCN7850: support for WoW (Wake on WLAN)
* WCN7850: device-tree bindings

ath11k

* QCA6390: device-tree bindings

8c62617295 wifi: mac80211: remove DEAUTH_NEED_MGD_TX_PREP 
This flag is annoying because it puts a lot of logic into mac80211
that could just as well be in the driver (only iwlmvm uses it) and
the implementation is also broken for MLO.

Remove the flag in favour of calling drv_mgd_prepare_tx() without
any conditions even for the deauth-while-assoc case. The drivers
that implement it can take the appropriate actions, which for the
only user of DEAUTH_NEED_MGD_TX_PREP (iwlmvm) is a bit more tricky
than the implementation in mac80211 is anyway, and all others have
no need and can just exit if info->was_assoc is set.

3f5d7ff7c5 wifi: mac80211: Use the link BSS configuration for beacon processing 
The beacon processing should be fully done in the context of the link.
This also resolves a bug with CQM handling with MLO as in such a case
the RSSI thresholds configuration is maintained in the link context and
not in the interface context.

a7e5793035 wifi: nl80211: don't give key data to userspace 
When a key is requested by userspace, there's really no need
to include the key data, the sequence counter is really what
userspace needs in this case. The fact that it's included is
just a historic quirk.

Remove the key data.

94833addfa net: thunderx: Unembed netdev structure 
Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_devices from struct lmac by converting them
into pointers, and allocating them dynamically. Use the leverage
alloc_netdev() to allocate the net_device object at
bgx_lmac_enable().

The free of the device occurs at bgx_lmac_disable().

 Do not free_netdevice() if bgx_lmac_enable() fails after lmac->netdev
is allocated, since bgx_lmac_disable() is called if bgx_lmac_enable()
fails, and lmac->netdev will be freed there (similarly to lmac->dmacs).

3a158e2e8e Merge branch 'selftests-net-switch-pmtu-sh-to-use-the-internal-ovs-script' 
Aaron Conole says:

====================
selftests: net: Switch pmtu.sh to use the internal ovs script.

Currently, if a user wants to run pmtu.sh and cover all the provided test
cases, they need to install the Open vSwitch userspace utilities.  This
dependency is difficult for users as well as CI environments, because the
userspace build and setup may require lots of support and devel packages
to be installed, system setup to be correct, and things like permissions
and selinux policies to be properly configured.

The kernel selftest suite includes an ovs-dpctl.py utility which can
interact with the openvswitch module directly.  This lets developers and
CI environments run without needing too many extra dependencies - just
the pyroute2 python package.

This series enhances the ovs-dpctl utility to provide support for set()
and tunnel() flow specifiers, better ipv6 handling support, and the
ability to add tunnel vports, and LWT interfaces.  Finally, it modifies
the pmtu.sh script to call the ovs-dpctl.py utility rather than the
typical OVS userspace utilities.  The pmtu.sh can still fall back on
the Open vSwitch userspace utilities if the ovs-dpctl.py script can't
be used.

b7ce46fc61 selftests: net: Use the provided dpctl rather than the vswitchd for tests. 
The current pmtu test infrastucture requires an installed copy of the
ovs-vswitchd userspace.  This means that any automated or constrained
environments may not have the requisite tools to run the tests.  However,
the pmtu tests don't require any special classifier processing.  Indeed
they are only using the vswitchd in the most basic mode - as a NORMAL
switch.

However, the ovs-dpctl kernel utility can now program all the needed basic
flows to allow traffic to traverse the tunnels and provide support for at
least testing some basic pmtu scenarios.  More complicated flow pipelines
can be added to the internal ovs test infrastructure, but that is work for
the future.  For now, enable the most common cases - wide mega flows with
no other prerequisites.

Enhance the pmtu testing to try testing using the internal utility, first.
As a fallback, if the internal utility isn't running, then try with the
ovs-vswitchd userspace tools.

Additionally, make sure that when the pyroute2 package is not available
the ovs-dpctl utility will error out to properly signal an error has
occurred and skip using the internal utility.

51458e1084 selftests: openvswitch: Support implicit ipv6 arguments. 
The current iteration of IPv6 support requires explicit fields to be set
in addition to not properly support the actual IPv6 addresses properly.
With this change, make it so that the ipv6() bare option is usable to
create wildcarded flows to match broad swaths of ipv6 traffic.

fefe3b7d6b selftests: openvswitch: Add support for tunnel() key. 
This will be used when setting details about the tunnel to use as
transport.  There is a difference between the ODP format between tunnel():
the 'key' flag is not actually a flag field, so we don't support it in the
same way that the vswitchd userspace supports displaying it.
