8c739d8d79 iwlwifi: mvm: Allow retries for probe responses
When hostapd sends a probe response, it does not request an
acknowledgment on the probe response. This setting is propagated
to the driver and FW from mac80211, and as a result probe responses
are transmitted only once without retries. In congested
environments, this reduces the likelihood for finding the AP.

To overcome this, enable acknowledgment and retries for probe
responses, even in case no acknowledgment is requested. In such
a case the retry limit is set to 3.

cfbc6c4c5b iwlwifi: mvm: support mac80211 TXQs model
Move to use the new mac80211 TXQs implementation. This has
quite a few benefits for us. We can get rid of the awkward
mapping of DQA to mac80211 queues. We can stop buffering
traffic while waiting for the queue to be allocated. We can
also use mac80211 AMSDUs instead of building it ourselves.

The usage is pretty simple:
Each ieee80211_txq contains iwl_mvm_txq. There is such a
queue for each TID, and one for management frames. We keep
having static AP queues for probes and non-bufferable MMPDUs,
along with broadcast and multicast queues. Those are being
used from the "old" TX invocation path - iwl_mvm_mac_tx.

When there is a new frame in a TXQ, iwl_mvm_mac_wake_tx is
being called, and either invokes the TX path, or allocates
the queue if it does not exist.

Most of the TX path is left untouched, although we can consider
cleaning it up some more, for example get rid of the duplication
of txq_id in both iwl_mvm_txq and iwl_mvm_dqa_txq_info.

70dc179dd9 iwlwifi: mvm: remove dead code
In iwl_mvm_tx_skb_non_sta(), in case of managed interface,
the AP station was supposed to be used for multicast frames
instead of the auxiliary station to avoid frames possibly
sent to an absent P2P GO. However, when moving to DQA mode,
this was broken as no valid queue was assigned. This is fixed
by a recent patch that directs all non-offchannel traffic to
ap station earlier in the TX path. However, the broken, and
now dead code, remained. Remove it.

f3f240f973 iwlwifi: mvm: remove queue_info_lock
All the queue management code runs under mvm->mutex, so there are
only very few cases of accessing the data structures without it:
 * TX path, which doesn't take any locks anyway
 * iwl_mvm_wake_sw_queue() and iwl_mvm_stop_sw_queue() where we
   just (atomically) read a bitmap, so the lock isn't needed.

Therefore, we can remove the spinlock. This enables some cleanup
in the ugly locking in iwl_mvm_inactivity_check().

724fe7710a iwlwifi: mvm: kill INACTIVE queue state
We don't really need this state: instead of having an inactive
state where we can awaken zombie queues again if needed, just
keep them in their normal state unless a new queue is actually
needed and there's no other way of getting one.

We do this here by making the inactivity check not free queues
unless instructed that we now really need to allocate one to a
specific station, and in that case it'll just free the queue
immediately, without doing any inactivity step inbetween.

The only downside is a little bit more processing in this case,
but the code complexity is lower.

Additionally, this fixes a corner case: due to the way the code
worked, we could only ever reuse an inactive queue if it was
the reserved queue for a station, as iwl_mvm_find_free_queue()
would never consider returning an inactive queue.

1a19c139be iwlwifi: mvm: avoid sending too many BARs
When we receive TX response, we may release a few packets
due to a hole that was closed in the transmission window.

However, if that frame failed, we will mark all the released
frames as failed and will send multiple BARs.

This affects statistics badly, and cause unnecessary frames
transmission.

Instead, mark all the following packets as success, with the
desired result of sending a bar for the failed frame only.

86e177d80f iwlwifi: mvm: add NOA and CSA to a probe response
A probe response built by a P2P GO should contain:
1. CSA/eCSA IE when relevant
2. If the corresponding probe request had P2P IE, then
need to add P2P IE with NOA attributes.

However, the NOA attributes and the updated channel switch
counter are known only to the FW. The solution is that FW
will send a notification with the relevant probe response
data and the driver will save it and update the probe
response accordingly.

2210f6959d iwlwifi: set the tid for non-QOS frames to zero
The tid for Non-QOS frames is set to IWL_MAX_TID_COUNT. This value
is also used for configuring the queue for non-QOS data. However, this
tid is used by the FW for management queues. As a result, the FW
does not encrypt non-QOS data frames.

Fix this by setting the tid for non-QOS data frames to zero, which
is a valid value for data frames in the FW.

This also fixes a bug in sending multicast frames, where the queues
are allocated with tid == 0, but are sent with tid == 8, which may
lead to unexpected behavior.

0eac9abace iwlwifi: mvm: fix TSO with highly fragmented SKBs
Our hardware has a limited amount of buffer descriptors
for each Tx packet. Because of that, there is a short
piece of code that makes sure that that we don't push too
many subframes in an A-MSDU because of subframes needs 2
buffer descriptors. This code also takes into account the
number of fragment of the skb since we also need a buffer
descriptor for each fragment in the skb.

This piece of code though didn't check that the resulting
number of subframes wasn't 0.

A user reported that using NFS client, he could get skbs
that are so fragmented that the code mentioned above
returned 0 for the number of subframes making
skb_gso_segment fail and subconsequently iwlwifi would WARN.

Fix this by make sure that num_subframes is at least 1.

334167decf iwlwifi: mvm: set the correct tid when we flush the MCAST sta
The tid being used for the queue (cab_queue) for the MCAST
station has been changed recently to be 0 (for BE).
The flush path still flushed only the special tid (15)
which means that the firmware wasn't flushing the right
queue and we could get a firmware crash upon remove
station if we had an MCAST packet on the ring.

The current code that flushes queues for a station only
differentiates between internal stations (stations that
aren't instantiated in mac80211, like the MCAST station)
and the non-internal ones.
Internal stations can be either: BCAST (beacons), MCAST
(for cab_queue), GENERAL_PURPOSE (p2p dev, and sniffer
injection). The internal stations can use different tids.

To make the code simpler, just flush all the tids always
and add the special internal tid (15) for internal
stations. The firmware will know how to handle this even
if we hadn't any queue mapped that that tid.

9f66a397c8 iwlwifi: mvm: rs: add ops for the new rate scaling in the FW
This patch introduces a new instance of rate_control_ops for
the new API (adding only empty stubs here and the subsequent
patches in the series will fill in the implementation).
The decision which API to use is done during the register
step according to FW TLV.

2f7a386319 iwlwifi: rename the temporary name of A000 to the official 22000
The family name A000 was just a place-holder when we didn't know what
the official name would be yet.  Now we know that the family name is
22000, so rename all occurrences accordingly.

087428d397 iwlwifi: mvm: support MGMT frames in compressed BA
In A000 family, compressed BA notifs can include MGMT
frames, so don't fail RXs in such a case.

While at it, since in A000 the TID for MGMT frames is
15, treat it in the RX flow as if received TID 8. This
way we won't require special handling of this TID.

b13f43a485 iwlwifi: mvm: fix packet injection
We need to have a station and a queue for the monitor
interface to be able to inject traffic. We used to have
this traffic routed to the auxiliary queue, but this queue
isn't scheduled for the station we had linked to the
monitor vif.

Allocate a new queue, link it to the monitor vif's station
and make that queue use the BE fifo.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=196715

6aa7de0591 locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE()
Please do not apply this to mainline directly, instead please re-run the
coccinelle script shown below and apply its output.

For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't harmful, and changing them results in
churn.

However, for some features, the read/write distinction is critical to
correct operation. To distinguish these cases, separate read/write
accessors must be used. This patch migrates (most) remaining
ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following
coccinelle script:

----
// Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and
// WRITE_ONCE()

// $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch
