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.

Instead of iterating all the queues after having potentially
changed some queue configurations, rechecking if that was done,
mark the ones that do need a TID change explicitly in a bitmap
and use that to send the change to the firmware.
While at it, also rename iwl_mvm_change_queue_owner() to
iwl_mvm_change_queue_tid() since that's more obvious - the
"kind" of owner isn't immediately clear right now.

We set the queue to this state, only to pretty much immediately
move it out of it again. However, we can't even hit any of the
code that checks if the queue is reconfiguring, because all of
this happens under mvm->mutex and we hold the all the way from
marking the queue as RECONFIGURING to marking it as READY again.
Additionally, the queue that became RECONFIGURING would've been
in SHARED state before, and it can safely stay in that state. In
case of errors, it previously would have stayed in RECONFIGURING
which it could never have left again.
Remove the state entirely and just track the queues that need to
be reconfigured in a separate, local, bitmap.

We currently reconfigure the queues after the inactivity check,
but only in one of the two callers. This might leave queues in
a state where the TID owner is wrong, if called when reserving
a queue for a new station.
Clean this up and do the reconfiguration inside the inactivity
check function. This requires changing the locking, but one of
the two places already holds the mvm mutex and the other easily
can.

Debug data dump is not working in flows that stop the device is used
in their error handling. During these flows the op mode mutex is
locked until the device stops. Because of that, any assert generated
from the firmware can be handled only after the device already
stopped.
Since dumping cannot occour after stopping the device, split the the
dump function to two parts, Part that handles locking, and the part
that starts the actual dumping and call the second part in the op mode
stop device function.

Currently in case of DCM with P2P GO where BSS DTIM interval < 220 msec
the fw fails to allocate events for the P2P GO dtim due to long passive
scan events.
Fix this by requesting all scans in this scenario to be fragmented with
fast balance scan time settings. The only exception is in case
fragmented scan was planned to be set due to low latency or high
throughput reason, set the scan timing as planned.

we were building AMSDU only in transport layer, and gen2

gen2 "non-pcie-amsdu" path.

In the past, we needed to program the keys when entering D3. This was
since we replaced the image. However, now that there is a single
image, this is no longer needed. Note that RSC is sent separately in
a new command. This solves issues with newer devices that support PN
offload. Since driver re-sent the keys, the PN got zeroed and the
receiver dropped the next packets, until PN caught up again.

In this case, the packet with new mac address will be dropped

Furtherly, disable vlan filter when enable promisc by user

Finally, since CONFIG_THERMAL can be =m, the Makefile fails to pick up the

cxgb4_thermal_init/cxgb4_thermal_remove files, so the Makefile has to
be adapted as well to work for both CONFIG_THERMAL=y and =m.

Currently Rx refill is done when the number of required descriptors is
above 1/8 queue size. With a default of 1024 entries per queue the
threshold is 128 descriptors.
There is intention to increase the queue size to 8196 entries.
In this case threshold of 1024 descriptors is too large and can hurt
latency.
Add another limitation to Rx threshold to be at most 256 descriptors.

The DECAP_ECN0 trap will be used to trap packets where the overlay
packet is marked with Non-ECT, but the underlay packet is marked with
either ECT(0), ECT(1) or CE. When trapped, such packets will be counted
as errors by the VxLAN driver and thus provide better visibility.
The NVE_ENCAP_ARP trap will be used to trap ARP packets undergoing NVE
encapsulation. This is needed in order to support E-VPN ARP suppression,
where the Linux bridge does not flood ARP packets through tunnel ports
in case it can answer the ARP request itself.
Note that all the packets trapped via these traps are marked with
'offload_fwd_mark', so as to not be re-flooded by the Linux bridge
through the ASIC ports.

The TNQDR register configures the default QoS settings for NVE
encapsulation.
It will be used to set the default DSCP of each port to 0, so that when
DSCP is set to inherit and the overlay packet does not have an IP header
the outer DSCP will be set to 0, in accordance with the software data
path.
