Macros CL_SNPRINTF and CL_PRINTF are always used in that order. The first
formats info into a buffer, and the second dumps it with printk. As the
debug system in rtlwifi has a macro that does this with a single call,
it seems reasonable to use it instead. An additional benefit is that the
debug level can be set when loading the driver used by the wifi device.

than the port limit is aggregated in this case. ex. 15 instead of

When assocaiting to an AP , mwifiex set supported data rates
based on target AP's capability. For 5G AP(11a mode), a/n/ac mode
would possibly be set.
However, for some chips which dont support 11AC mode current config_bands
will be used instead.
For example, if we join an IBSS in 11b mode ,adapter->config_bands
will be set to 1(11b mode). Then we leave IBSS ,and try to connect
5G a/n mode AP. At this time , only 11b mode data rates will be
supported in assoc request , which result in assoc failure with
reason code 18: Association denied due to requesting station not
supporting all rates.
This patch fix such a cornel case, by adding additional check for
current chip's 11ac capability.

The NoA duration for a GO is half the beacon interval
and a concurrent context like a STA can be active only
for that duration, before switching back to the GO's
operating channel.
Currently, when multiple beacons are missed, the dwell
time for the STA context is extended to improve the
chances of receiving a beacon. But the NoA is not updated
and this will cause problems since the GO is offline
for a period that is longer than the advertised duration.
Fix this by ensuring that the NoA is updated first before
extending the time slot for the STA context. Also make
sure that non-periodic NoA is used for a one-time, longer
absence period.

multiple contexts are active and an offchannel

Fix this by clearing the duration only if there
is no pending offchannel request.

* Switch to non-periodic NoA when starting a scan operation

* Make sure that periodic NoA is advertised again when

Reason is the following: when removing Rx vring
(wil_netdev_ops.ndo_stop -> wil_stop -> wil_down -> __wil_down -> wil_rx_fini),
Rx interrupt occurs. It trigger Rx NAPI, calling wil_rx_handle() that reaps
(already cleaned) buffer, causing skb referring to garbage memory being set into reorder buffer.
Then, network stack trying to access this buffer and fails.
Prevent Rx NAPI from being scheduled if device going to stop. Bit wil_status_napi_en reflects
NAPI enablement state, check it when triggering Rx NAPI.
Testing shows that check for wil_status_napi_en sometimes gets negative, and new error message
get printed - in this case kernel oops would be observed. Original oops is no more reproducible.
This change requires also changes in the AP flows.
Properly enable/disable NAPI for the AP. Make sure Rx VRING is disabled
when resetting target.
For this, promote __wil_up() and __wil_down() to the module scope, and use it
in the relevant flows.

Scanning is curently broken when two channel contexts
are active. For example in a P2P-GO/STA setup, the
offchannel timer allows HZ / 10 to elapse before initiating
a switch to the next scan channel from the current operating
channel, which in this case would be the P2P-GO context.
But, the channel context timer might decide to switch
to the STA context when an SWBA comes early and a beacon
is sent out. Since pending offchannel requests are processed
in EVENT_BEACON_PREPARE, this causes inconsistent scanning.
Fix this by making sure that a context switch happens
before processing the pending offchannel request. This
also makes sure that active channel contexts will always
have higher priority than offchannel operations and the
scan sequence looks like this:
p2p-go, sta, p2p-go, offchannel, p2p-go, sta, p2p-go, offchannel,.....
The oper-channel is p2p-go, so the STA context has to
switch to p2p-go again before switching offchannel.

The start time field in the NoA attribute needs to be
updated based on the TSF timer when an absence notification
is sent by the P2P GO. When two channel contexts are active,
continuous, cyclic NoA is announced by setting the count value to 255,
but the start time is updated only once, for one beacon and
the same value is sent in all subsequent beacons, even
though the timestamp keeps moving.
Fix this by removing the check for 'periodic_noa_duration'
and assign the interface's start_time/duration values directly
when there is more than one active context.

If a station interface is already assigned to a context
and is active and a second interface of type AP is added,
then beaconing on the new interface has to be begin only
after the BSS_CHANGED_BEACON_ENABLED flag is sent by mac80211
to the driver.
But, since we issue ATH_CHANCTX_EVENT_ENABLE_MULTICHANNEL as soon
as a new channel context is added, a switch occurs almost immediately
before BSS_CHANGED_BEACON_ENABLED is received. When a HW reset
is done for the new context, beacons are enabled for the
interface since "enable_beacon" in the BSS config maintained
in mac80211 is true - but the driver hasn't been notified yet.
This causes a panic, since the beacon interval is zero for this
interface and ath9k_cmn_beacon_config_ap() doesn't have a safety check.
Fix this panic by checking if the beacon params has been cached
for this context and use the "enable_beacon" flag maintained
locally in the driver. Also, recalculate the summary data
after the beacon params have been cached when BSS_CHANGED_BEACON_ENABLED
is received.

In channel context mode, when a new context is added,
mac80211 issues a bss_info_changed() notfication when
preparing the connection for the new interface/context.
But, this is done prior to the mgd_prepare_tx() call which
is where we switch to the new context. Since the current
context will be different when the earlier bss_info_changed()
is handled, the beacon information for the VIF is not
updated, but discarded since the rules for the current context
disallows it.
In the subsequent association process for the new context/vif,
this becomes a problem because the beacon parameters are invalid.
This causes problems with the TSF timer, causing large jumps.
To fix this, check if the beacon info is being updated for a
different context and if so, allow it without any checks since
we limit the max. interfaces to two anyway.

"Not that much content this time. Some RCU cleanups, crypto
performance improvements, and various patches all over,
rather than listing them one might as well look into the
git log instead."

The auxiliary station is being handled using the internal
station helper functions, clean that up and make the helpers
static.

Unify all the functions that handle the per-interface broadcast
station and make them have mvm and vif parameters. While at it,
add a new function to allocate the broadcast station instead of
open-coding it, and make the combined alloc+send and free+send
functions use the alloc/free & send functions.

There are a few places that can call the function
iwl_mvm_mac_get_queues_mask() instead of open-coding the
equivalent, so do that. This requires changing it to return
the multicast queue as part of the bitmap, which broke GO
mode because including it in the broadcast station queues
seems to confuse the firmware, so work around that.
Also, the API defines that the CAB queue shouldn't be
included in the TFD queue mask, adjust the comment
accordingly (not a bug).

Instead of checking whether a given station is the first to
be added on a client interface check for the new TDLS flag
and warn in the unexpected cases.

The queue handling is a bit unclear - we have an array for
stop_count[IWL_MAX_HW_QUEUES] but indices really are the
mac80211 queue numbers. Change the array to be only of the
right size for mac80211 queues (IEEE80211_MAX_QUEUES) and
rename it to be clearer.
While at it, also remove the unused transport queue stop
bitmap in mvm.

Move all FIFO definitions together into the firmware API
header file and use the same enum/naming scheme for the
command FIFO.

The firmware would like to have a MAC context (unassoc)
before the AP station is removed (we do this) but would
like to keep the BSSID until after it is removed, so we
need to send two commands - one with the BSSID before
and one without the BSSID after.
In order to do this, we need to store the BSSID as it
will have been cleared by mac80211 by the time we get
notified of the disassociation. Also pass it around as
an override to the various functions needing it, and
keep taking it from the mac80211 data otherwise. This
avoids having to keep track of the BSSID in all modes.

During a channel switch we should tell the firmware to disable TX
temporarily and re-enable it after the switch is done.

Currently the firmware is handling this, but that is wrong as it then
needs to assume a certain command queue, therefore this should be in
the driver; add it here so it can be removed from the firmware in the
future.
