The nl80211 attribute NL80211_ATTR_CSA_C_OFF_BEACON should be nested
inside NL80211_ATTR_CSA_IES, but commit ee4bc9e75811d2c0cb5f2a2fc5b5
("nl80211: enable IBSS support for channel switch announcements")
added a check in the outer message attributes.
Fix channel switch calls by removing the erroneus condition.

mac80211_hwsim canceled beacon_timer on any vif changing from enabled
to disabled beaconing. This breaks cases where there are multiple
beaconing vifs and only one of them is removed. Fix this by tracking
beaconing status per vif and disable beacon_timer only if no active vif
remain with beaconing enabled.

Implement the required procedures for mesh channel switching as defined
in the IEEE Std 802.11-2012 section 10.9.8.4.3 and also handle the CSA
and MCSP elements as followed:
* Add the function for updating the beacon and probe response frames
with CSA and MCSP elements during the period of switching to the new
channel. Both CSA and MCSP elements must be included in beacon and
probe response frames until the intended channel switch time.
* The ifmsh->csa_settings is set to NULL and the CSA and MCSP elements
will then be removed from the beacon or probe response frames once the
new channel is switched to.

the previous mode. Also, move the ieee80211_send_action_csa

Process the CSA frame according to the procedures define in IEEE Std
802.11-2012 section 10.9.8.4.3 as follow:
* The mesh channel switch parameters element (MCSP) must be availabe.
* If the MCSP's TTL is 1, drop the frame but still process the CSA.
* If the MCSP's precedence value is less than or equal to the current
precedence value, drop the frame and do not process the CSA.
* The CSA frame is forwarded after TTL is decremented by 1 and the
initiator field is set to 0. Transmit restrict field and others
are maintained as is.
* No beacon or probe response frame are handled here.
Also, introduce the debug message used for mesh CSA purpose.

This patch fixes errors in the mesh powersave logic which
cause that remote peers do not get peer power mode change
notifications and mesh peer service periods (MPSPs) got
stuck.
When closing a peer link, set the (now invalid) peer-specific
power mode to 'unknown'.
Avoid overhead when local power mode is unchanged.
Reliably clear MPSP flags on peering status update.
Avoid MPSP flags getting stuck by not requesting a further
MPSP ownership if we already are an MPSP owner.

To use DFS in IBSS mode, userspace is required to react to radar events.
It can inform nl80211 that it is capable of doing so by adding a
NL80211_ATTR_HANDLE_DFS attribute when joining the IBSS.
This attribute is supplied to let the kernelspace know that the
userspace application can and will handle radar events, e.g. by
intiating channel switches to a valid channel. DFS channels may
only be used if this attribute is supplied and the driver supports
it. Driver support will be checked even if a channel without DFS
will be initially joined, as a DFS channel may be chosen later.

When the driver requests to move to STATIC or DYNAMIC SMPS,
we send an action frame to each associated station and
reconfigure the channel context / driver.
Of course, non-MIMO stations are ignored.
The beacon isn't updated. The association response will
include the original capabilities. Stations that associate
while in non-OFF SMPS mode will get an action frame right
after association to inform them about our current state.
Note that we wait until the end of the EAPOL. Sending an
action frame before the EAPOL is finished can be an issue
for a few clients. Clients aren't likely to send EAPOL
frames in MIMO anyway.
When the SMPS configuration gets more permissive (e.g.
STATIC -> OFF), we don't wake up stations that are asleep
We remember that they don't know about the change and send
the action frame when they wake up.
When the SMPS configuration gets more restrictive (e.g.
OFF -> STATIC), we set the TIM bit for every sleeping STA.
uAPSD stations might send MIMO until they poll the action
frame, but this is for a short period of time.

wlcore configures different dwell times according to number
of active interfaces (in order to prevent hurting VO during
scan).
However, determining active vif only according to
bss_conf->idle is not explicit enough, and might result
in non-started vifs being counted as started as well
(e.g. unassociated sta during sta).
Fix it by checking for explicit conditions according
to the vif type.

Make sure the FW is awake when entering recovery. This is useful for
reading the FW panic log and also some FW registers giving us crash

We must do this before interrupts are disabled since we rely on an
interrupt to complete the wakeup.

The parent socket is not used inside the L2CAP core anymore. We only lock
it to indirect access through the new_connection() callback. The hold of
the socket lock was moved to the new_connection() callback.
Inside L2CAP core the channel lock is now used in l2cap_le_conn_ready()
and l2cap_conn_ready() to protect the execution of these two functions
during the handling of new incoming connections.
This change remove the socket lock usage from L2CAP core while keeping

we got rid of __l2cap_state_change(). And l2cap_state_change() doesn't lock
the socket anymore, instead the socket is locked inside the ops callback for

It makes the code safer because in some we were using a unlocked version,

the locked version.

In both places that we use the defer callback the socket lock is held for
a indirect sk access inside __l2cap_change_state() and chan->ops->defer(),
all the rest of the code between lock_sock() and release_sock() is
already protected by the channel lock and won't be affected by this
change.
We now use l2cap_change_state(), the locked version of the change state
function, and the defer callback does the locking itself now. This does
not affect other uses of the defer callback.
