f7c125bd79 net: mhi: Fix memory leak in mhi_net_dellink()
MHI driver registers network device without setting the
needs_free_netdev flag, and does NOT call free_netdev() when
unregisters network device, which causes a memory leak.

This patch calls free_netdev() to fix it since netdev_priv
is used after unregister.

2fd450cd83 ipasdv4/tcp_ipv4: remove redundant assignment

it's unnecessary to assign TCP_SEQ_STATE_LISTENING to it, so we can remove it.

e4041be97b octeon_ep: fix potential memory leak in octep_device_setup()
When occur unsupported_dev and mbox init errors, it did not free oct->conf

8a30b30b26 Merge branch 'ibmvnic-affinity-hints'
Nick Child says:

====================
ibmvnic: Introduce affinity hint support

This is a patchset to do 3 things to improve ibmvnic performance:
    1. Assign affinity hints to ibmvnic queue irq's
    2. Update affinity hints on cpu hotplug events
    3. Introduce transmit packet steering (XPS)

NOTE: If irqbalance is running, you need to stop it from overriding
  our affinity hints. To do this you can do one of:
   - systemctl stop irqbalance
   - ban the ibmvnic module irqs
      - you must have the latest irqbalance v9.2, the banmod argument was broken before this
      - in /etc/sysconfig/irqbalance -> IRQBALANCE_ARGS="--banmod=ibmvnic"
      - systemctl restart irqbalance

df8f66d02d ibmvnic: Update XPS assignments during affinity binding
Transmit Packet Steering (XPS) maps cpu numbers to transmit
queues. By running the same connection on the same set of cpu's,
contention for the queue and cache miss rate can be minimized.
When assigning a cpu mask for a tranmit queues irq number, assign
the same cpu mask as the set of cpu's that XPS should use for that
queue.

92125c3a60 ibmvnic: Add hotpluggable CPU callbacks to reassign affinity hints
When CPU's are added and removed, ibmvnic devices will reassign
hint values. Introduce a new cpu hotplug state CPUHP_IBMVNIC_DEAD
to signal to ibmvnic devices that the CPU has been removed and it
is time to reset affinity hint assignments. On the other hand,
when CPU's are being added, add a state instance to
CPUHP_AP_ONLINE_DYN which will trigger a reassignment of affinity
hints once the new CPU's are online. This implementation is based
on the virtio_net driver.

2c925db0a7 net/mlx5e: Support enhanced CQE compression
CQE compression feature improves performance by reducing PCI bandwidth
bottleneck on CQEs write.
Enhanced CQE compression introduced in ConnectX-6 and it aims to reduce
CPU utilization of SW side packets decompression by eliminating the
need to rewrite ownership bit, which is likely to cost a cache-miss, is
replaced by validity byte handled solely by HW.
Another advantage of the enhanced feature is that session packets are
available to SW as soon as a single CQE slot is filled, instead of
waiting for session to close, this improves packet latency from NIC to
host.

Performance:
Following are tested scenarios and reults comparing basic and enahnced
CQE compression.

setup: IXIA 100GbE connected directly to port 0 and port 1 of
ConnectX-6 Dx 100GbE dual port.

Case #1 RX only, single flow goes to single queue:
IRQ rate reduced by ~ 30%, CPU utilization improved by 2%.

Case #2 IP forwarding from port 1 to port 0 single flow goes to
single queue:
Avg latency improved from 60us to 21us, frame loss improved from 0.5% to 0.0%.

Case #3 IP forwarding from port 1 to port 0 Max Throughput IXIA sends
100%, 8192 UDP flows, goes to 24 queues:
Enhanced is equal or slightly better than basic.

Testing the basic compression feature with this patch shows there is
no perfrormance degradation of the basic compression feature.

9d8e536d36 ALSA: memalloc: Try dma_alloc_noncontiguous() at first
The latest fix for the non-contiguous memalloc helper changed the
allocation method for a non-IOMMU system to use only the fallback
allocator.  This should have worked, but it caused a problem sometimes
when too many non-contiguous pages are allocated that can't be treated
by HD-audio controller.

As a quirk workaround, go back to the original strategy: use
dma_alloc_noncontiguous() at first, and apply the fallback only when
it fails, but only for non-IOMMU case.

We'll need a better fix in the fallback code as well, but this
workaround should paper over most cases.

Alex Elder says:

====================
dt-bindings: net: qcom,ipa: relax some restrictions

The first patch in this series simply removes an unnecessary
requirement in the IPA binding.  Previously, if the modem was doing
GSI firmware loading, the firmware name property was required to
*not* be present.  There is no harm in having the firmware name be
specified, so this restriction isn't needed.

The second patch restates a requirement on the "memory-region"
property more accurately.

These binding changes have no impact on existing code or DTS files.
These aren't really bug fixes, so no need to back-port.

7a6ca44c1e dt-bindings: net: qcom,ipa: restate a requirement
Either the AP or modem loads GSI firmware.  If the modem-init
property is present, the modem loads it.  Otherwise, the AP loads
it, and in that case the memory-region property must be defined.

Currently this requirement is expressed as one or the other of the
modem-init or the memory-region property being required.  But it's
harmless for the memory-region to be present if the modem is loading
firmware (it'll just be ignored).

Restate the requirement so that the memory-region property is
required only if modem-init is not present.

9d26628a4c dt-bindings: net: qcom,ipa: remove an unnecessary restriction
Commit d8604b209e ("dt-bindings: net: qcom,ipa: add firmware-name
property") added a requirement for a "firmware-name" property that
is more restrictive than necessary.

If the AP loads GSI firmware, the name of the firmware file to use
may optionally be provided via a "firmware-name" property.  If the
*modem* loads GSI firmware, "firmware-name" doesn't need to be
supplied--but it's harmless to do so (it will simply be ignored).

Remove the unnecessary restriction, and allow "firware-name" to be
supplied even if it's not needed.

'time' is the local variable of run_test() function, while 'max_time' is
the local variable of do_transfer() function. So in do_transfer(),
$max_time should be used, not $time.

Please note that here $time == $max_time so the behaviour is not changed
but the right variable is used.
