19125cb059 iwlwifi: mvm: Increase session protection time after CS
After switching to a new channel, driver schedules session protection
time event in order to hear the beacon on the new channel.
The duration of the protection is two beacon intervals.
However, since we start to switch slightly before beacon with count 1, in
case we don't hear (or AP doesn't transmit) the very first beacon on the
new channel the protection ends without hearing any beacon at all.
At this stage the switch is not complete, the queues are closed and the
interface doesn't have quota yet or TBTT events. As the result, we are
stuck forever waiting for iwl_mvm_post_channel_switch() to be called.

Fix this by increasing the protection time to be 3 beacon intervals and
in addition drop the connection if the time event ends before we got any
beacon.

4b7f7ee2a5 iwlwifi: align timestamp cancel with timestamp start
Canceling the periodic timestamp work should be
done in the opposite flow to where it was started.
This also prevents from sending the MARKER command
during the mac_stop flow - causing a false queue hang
(FW is no longer there to send a response).

ecaf71de41 iwlwifi: mvm: rs: introduce new API for rate scaling
New devices will have rate scaling algorithm running in the firmware.
With this feature, the driver's responsiblity is to provide an initial
configuration and to handle notifications regarding recent rates and
some other parameters. Debugfs hooks will be still available for
reading the current rate/statistics and setting a fixed rate.
The old API is supported so far, though both APIs cannot be used
simultaneously.

This is the first patch in the series. It adds a new TLV specifying
FW support for the new API and updates lq_sta to support two types
of rate scaling.

dac4df1c5f iwlwifi: mvm: support version 7 of the SCAN_REQ_UMAC FW command
Newer firmware versions (such as iwlwifi-8000C-34.ucode) have
introduced an API change in the SCAN_REQ_UMAC command that is not
backwards compatible.  The driver needs to detect and use the new API
format when the firmware reports it, otherwise the scan command will
not work properly, causing a command timeout.

Fix this by adding a TLV that tells the driver that the new API is in
use and use the correct structures for it.

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

The RCU lifetime on baid_data is unclear, so this adds a direct copy of the
rcu_ptr passed to the original callback. It may be possible to improve this
to just use baid_data->mvm->baid_map[baid_data->baid] instead.

dfdddd92a5 iwlwifi: mvm: allocate reorder buffer according to need
Now that we may have up to 256 entries per reorder buffer, and possibly up
to 16 queues, we can use a LOT of memory for this (64k for each station).
Allocate it according to what we need, which is of course much less for HT
stations (only 16k at a max of 16 queues).

However, this comes at the expense of complicating the code a bit to

7a20bcceed iwlwifi: mvm: don't send identical PHY_CTXT_CMD
When we have an AP which supports HT and a single HT
station is connected, we change the min_width from
NL80211_CHAN_WIDTH_20_NOHT to NL80211_CHAN_WIDTH_20. This
of course has no implication on the channel width but still
sends a command to the firmware.
Remember the last width that was sent and refrain from
sending unnecessary commands to the firmware.

Sending a PHY_CTXT_CMD to the firmware has a cost since it
recalculates the presence on the medium and because of that
it closes the transmit queues for a short while.

c8f54701bd iwlwifi: mvm: remove non-DQA mode
All the firmware versions the driver supports enable DQA, and thus
the only way to get non-DQA mode is to modify the source. Remove
this mode to simplify the code.

bf8b286f86 iwlwifi: mvm: defer setting IWL_MVM_STATUS_IN_HW_RESTART
A hardware/firmware error may happen at any point in time. In
particular, it might happen while mac80211 is in the middle of
a flow. We observed the following situation:
 * mac80211 is in authentication flow, in ieee80211_prep_connection()
 * iwlwifi firmware crashes, but no error can be reported at this
   precise point (mostly because the driver method is void, but even
   if it wasn't we'd just shift to a race condition)
 * mac80211 continues the flow, trying to add the AP station
 * iwlwifi has already set its internal restart flag, and so thinks
   that adding the station is part of the restart and already set up,
   so it uses the information that's supposed to already be in the
   struct

This can happen with any flow in mac80211 and with any information
we try to preserve across hardware restarts.

To fix this, only set a new HW_RESTART_REQUESTED flag and translate
that to IN_HW_RESTART once mac80211 actually starts the restart by
calling our start() method. As a consequence, any mac80211 flow in
progress at the time of the restart will properly finish (certainly
with errors), before the restart is attempted.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299.

37e474acc9 iwlwifi: mvm: fix mac80211 queue tracking
In the driver, we track which hardware queue is associated with
which mac80211 "hw_queue", in order to be able to stop and wake
it. When moving these bitmaps out of the queue_info structures,
the type of the bitmap was erroneously changed from u32 to u8,
presumably in order to save memory.

Turns out that u32 isn't needed, because the highest queue we
can ever tell mac80211 is always < 16, but a u16 definitely is
needed, queues >=8 do happen.

While at it, throw a BUILD_BUG_ON() into the place where we set
the limit (mvm->first_agg_queue) and a warning when it actually
gets put into the bitmap.

The consequence of this bug is that full HW queues associated
with such a too-high mac80211 number never stop higher layer
queues when full, and thus would simply drop all packets that
couldn't be enqueued to the hardware queue.
