All links were iterated over during processing ML info in Association
Request frame. However, the association link info will not be present in
the ML info and hence the following debug print is observed during ML
association (assoc link is 1):
MLD: No link match for link_id=1

Authenticator state machine ML info was set only when it was created.
However, if the association is tried again, the state machine will
already exist and hence the ML info will not be refreshed. This leads to
an issue where if in the subsequent association request, the MLD info is
different than the old info, validation of it will fail.
Fix this issue by refreshing the authenticator state machine's ML info

The nl80211 driver interface function mlme_event_mgmt_tx_status(),
filled in link_id only if the frame was the last transmitted on the
whole drv (driver) level. With co-hosted MLDs, there could be cases
where multiple frames are sent out by various interfaces (BSS) under the
same drv. Now while handling the TX status, only one interface will get
the proper link_id. Rest will get -1 and the event will be routed to the
first BSS always. If the frame was not sent from the first BSS this
leads to possibility of the frame getting dropped.
Hence to make the underlying link identification easier, modify
authentication and association frames to be always sent with the link
address as A1 and A3 for ease of TX status handling.

Add a QCA vendor command for registering NL80211_CMD_GET_STATION
response as a unicast event when there is a NL80211_CMD_GET_STATION
request from any userspace module.
The driver will send the unicast events with the same netlink port ID
which is used by userspace application for sending the registration
command. If multiple registration commands are received with different
netlink port IDs, the driver will send unicast event with each netlink
port ID separately.
Userspace application can deregister the unicast events with disable
configuration. The registrations will be removed automatically by the
driver when the corresponding netlink socket is closed.
This will help avoid multiple NL80211_CMD_GET_STATION requests from
different userspace applications in short span. The userspace
application which registers for the unicast event can avoid sending
NL80211_CMD_GET_STATION request again if the response is available with
a recently received unicast event.

If authentication fails repeatedly, e.g., because of a weak signal, the
link can end up in blocked state. If one of the nodes tries to establish
a link again before it is unblocked on the other side, it will block the
link to that other side. The same happens on the other side when it
unblocks the link. In that scenario, the link never recovers on its own.
To fix this, allow restarting authentication even if the link is in
blocked state, but don't initiate the attempt until the blocked period
is over. This reverts commit 09d96de09e ("mesh: Drop Authentication
frames from BLOCKED STA").

When we are configuring automatic channel selection, we are not able to
switch to a given DFS channel because when we are trying to move to a
DFS channel, the interface is disabled and enabled again. When the
interface is disabled and enabled we are setting iface's freq and
channel to 0 in setup_interface2() in case ACS is enabled, and now we
don't know to which channel we were trying to move. Now ACS will run and
the interface will be up in the channel that is suitable.
To fix this issue add a flag named is_ch_switch_dfs to check if the
channel switch request is for a DFS channel and we can use this in
setup_interface2() to decide whther we have to set iface's freq and
channel to 0 or not. This way iface's freq and channel will retain the
values while channel switching to a DFS channel when ACS is enabled.

when setting up a link on a DFS channel while the interface is not yet
enabled:
1. DFS link received CAC start event
2. If no radar detected, link setup succeeeds after CAC end
event is received. Else go to 3.
3. Radar detected on this link -> set radar_detected bit
4. CAC end received for the current freq -> Do not setup interface
as radar already detected. Clear radar_detected bit.
5. The driver sends channel switch event to switch to another channel
a. Switch to another DFS channel -> go to 1
b. Switch to non-DFS channel -> proceed to set up interface
Or when receiving a CAC start event when the interface is already set up:
1. DFS link already set up successfully
2. Radar detected on this link -> set radar_detected bit
a. Switch to DFS channel
a.1. CAC start -> clear radar_detected bit and partner RNR
a.2. If radar detected, go to 2.

b. Switch to non-DFS channel

Link ID is more accurate to specify the BSS for a radar event in some
corner cases, e.g., when there is a radar detection event and the driver
then switches to another DFS channel. There will then be two events
coming from the driver (CAC start and channel switch complete). In case
the CAC-start event comes first, hostapd still stores the previous
frequency and cannot find the correct link by calling
nl80211_get_mld_link_by_freq() with the new frequency.
