[PATCH AUTOSEL 6.7 26/58] wifi: mac80211: set station RX-NSS on reconfig

[Sasha Levin]

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit dd6c064cfc3fc18d871107c6f5db8837e88572e4 ]

When a station is added/reconfigured by userspace, e.g. a TDLS
peer or a SoftAP client STA, rx_nss is currently not always set,
so that it might be left zero. Set it up properly.

[PATCH AUTOSEL 6.7 27/58] wifi: mac80211: fix driver debugfs for vif type change

[Sasha Levin]

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 733c498a80853acbafe284a40468b91f4d41f0b4 ]

If a driver implements the change_interface() method, we switch
interface type without taking the interface down, but still will
recreate the debugfs for it since it's a new type. As such, we
should use the ieee80211_debugfs_recreate_netdev() function here
to also recreate the driver's files, if it is indeed from a type
change while up.

[PATCH AUTOSEL 6.7 28/58] wifi: mac80211: initialize SMPS mode correctly

[Sasha Levin]

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 86b2dac224f963be92634a878888222e1e938f48 ]

The SMPS mode is currently re-initialized too late, since
ieee80211_prep_channel() can be called again after we've
already done ieee80211_setup_assoc_link(), in case there's
some override of the channel configuration. Fix this.

[PATCH AUTOSEL 6.7 29/58] wifi: mac80211: adding missing drv_mgd_complete_tx() call

There's a call to drv_mgd_prepare_tx() and so there should
be one to drv_mgd_complete_tx(), but on this path it's not.
Add it.

[PATCH AUTOSEL 6.7 30/58] wifi: mac80211: accept broadcast probe responses on 6 GHz

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 62a6183c13319e4d2227473a04abd104c4f56dcf ]

On the 6 GHz band, probe responses are sent as broadcast to
optimise medium usage. However, without OCE configuration
we weren't accepting them, which is wrong, even if wpa_s is
by default enabling OCE. Accept them without the OCE config
as well.

[PATCH AUTOSEL 6.7 31/58] wifi: iwlwifi: do not announce EPCS support

[ Upstream commit a23c0af103e184bb1252dddddda040f6641bea7b ]

mac80211 does not have proper support for EPCS currently as that would
require changing the ECDA parameters if EPCS (Emergency Preparedness
Communications Service) is in use. As such, do not announce support for
it in the capabilities.
