Flush dbc requests when dbc is stopped and transfer rings are freed.
Failure to flush them lead to leaking memory and dbc completing odd
requests after resuming from suspend, leading to error messages such as:

When /dev/ttyDBC0 device is created then by default ECHO flag
is set for the terminal device. However if data arrives from
a peer before application using /dev/ttyDBC0 applies its set
of terminal flags then the arriving data will be echoed which
might not be desired behavior.

During the High-Speed Isochronous Audio transfers, xHCI
controller on certain AMD platforms experiences momentary data
loss. This results in Missed Service Errors (MSE) being
generated by the xHCI.
The root cause of the MSE is attributed to the ISOC OUT endpoint
being omitted from scheduling. This can happen when an IN
endpoint with a 64ms service interval either is pre-scheduled
prior to the ISOC OUT endpoint or the interval of the ISOC OUT
endpoint is shorter than that of the IN endpoint. Consequently,
the OUT service is neglected when an IN endpoint with a service
interval exceeding 32ms is scheduled concurrently (every 64ms in
this scenario).
This issue is particularly seen on certain older AMD platforms.
To mitigate this problem, it is recommended to adjust the service
interval of the IN endpoint to not exceed 32ms (interval 8). This
adjustment ensures that the OUT endpoint will not be bypassed,
even if a smaller interval value is utilized.

Commit 96c7bf8f6b3e ("usb: dwc3: gadget: Cleanup SG handling") updated
the TRB reclaim path to use the TRB CHN (Chain) bit to determine whether
a TRB was part of a chain. However, this inadvertently changed the
behavior of reclaiming the final TRB in some scatter-gather or short
transfer cases.
In particular, if the final TRB did not have the CHN bit set, the
cleanup path could incorrectly skip clearing the HWO (Hardware Own)
bit, leaving stale TRBs in the ring. This resulted in broken data
transfer completions in userspace, notably for MTP over FunctionFS.
Fix this by unconditionally clearing the HWO bit during TRB reclaim,
regardless of the CHN bit state. This restores correct behavior
especially for transfers that require ZLPs or end on non-CHN TRBs.

CMCI banks are not cleared during shutdown on Intel CPUs. As a side effect,
when a kexec is performed, CPUs coming back online are unable to
rediscover/claim these occupied banks which breaks MCE reporting.
Clear the CPU ownership during shutdown via cmci_clear() so the banks can
be reclaimed and MCE reporting will become functional once more.

The `dma_map_XXX()` functions can fail and must be checked using
`dma_mapping_error()`. This patch adds proper error handling for all
DMA mapping calls.
In `atl1_alloc_rx_buffers()`, if DMA mapping fails, the buffer is
deallocated and marked accordingly.
In `atl1_tx_map()`, previously mapped buffers are unmapped and the
packet is dropped on failure.
If `atl1_xmit_frame()` drops the packet, increment the tx_error counter.

Octeontx2-pf: extend link modes support
This series of patches adds multi advertise mode support along with
other improvements in link mode management code flow.
Patch1: Currently all SGMII modes 10/100/1000baseT are mapped with
single firmware mode. This patch updates these link modes
with corresponding firmware modes.
Patch2: Due to limitation in current kernel <-> firmware communication,
link modes are divided into multiple groups, and identified
with their group index.
Patch3: Adds support for multi advertise mode.

Current implementation considers only first advertise
mode and passes the same to firmware to process.
This patch extends code such that user can advertise
multiple modes on the given interface.
Below are high level changes:
1. Remove unnecessary speed/duplex/autoneg validation as its
already verified as part of "set_link_ksettings"
2. Since scratch csr framework designed to support single mode at a time,
use "shared firmware data" for multi mode support.

Arkadiusz Kubalewski says:
====================
dpll: add Reference SYNC feature
The device may support the Reference SYNC feature, which allows the
combination of two inputs into a input pair. In this configuration,
clock signals from both inputs are used to synchronize the DPLL device.
The higher frequency signal is utilized for the loop bandwidth of the DPLL,
while the lower frequency signal is used to syntonize the output signal of
the DPLL device. This feature enables the provision of a high-quality loop
bandwidth signal from an external source.
A capable input provides a list of inputs that can be bound with to create
Reference SYNC. To control this feature, the user must request a
desired state for a target pin: use ``DPLL_PIN_STATE_CONNECTED`` to
enable or ``DPLL_PIN_STATE_DISCONNECTED`` to disable the feature. An input
pin can be bound to only one other pin at any given time.
Verify pins bind state/capabilities:
$ ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/dpll.yaml \
--do pin-get \
--json '{"id":0}'
{'board-label': 'CVL-SDP22',
'id': 0,
[...]
'reference-sync': [{'id': 1, 'state': 'disconnected'}],
[...]}
Bind the pins by setting connected state between them:
$ ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/dpll.yaml \
--do pin-set \
--json '{"id":0, "reference-sync":{"id":1, "state":"connected"}}'

packet headers (or MTU if HW-GRO is disabled). The aggregation buffers
are filled with "device pages". Adjust the sizes of the page pool
recycling ring appropriately, based on ratio of the size of the
buffer on given ring vs system page size. Otherwise on a system
with 64kB pages we end up with >700MB of memory sitting in every
single page pool cache.
Correct the size calculation for the head_pool. Since the buffers
there are always small I'm pretty sure I meant to cap the size
at 1k, rather than make it the lowest possible size. With 64k pages
1k cache with a 1k ring is 64x larger than we need.

Test DSACK behavior with non contiguous ranges.
Without prior fix (tcp: fix tcp_ofo_queue() to avoid including
too much DUP SACK range) this would fail with:

If the new coming segment covers more than one skbs in the ofo queue,
and which seq is equal to rcv_nxt, then the sequence range
that is duplicated will be sent as DUP SACK, the detail as below,
in step6, the {501,2001} range is clearly including too much
DUP SACK range, in violation of RFC 2883 rules.
1. client > server: Flags [.], seq 501:1001, ack 1325288529, win 20000, length 500
2. server > client: Flags [.], ack 1, [nop,nop,sack 1 {501:1001}], length 0

6. server > client: Flags [.], ack 2001, [nop,nop,sack 1 {501:2001}], length 0

net: dsa: ks8995: Fix up bindings
After looking at the datasheets for KS8995 I realized this is
a DSA switch and need to have DT bindings as such and be implemented
as such.
This series just fixes up the bindings and the offending device tree.
The existing kernel driver which is in drivers/net/phy/spi_ks8995.c
does not implement DSA. It can be forgiven for this because it was
merged in 2011 and the DSA framework was not widely established
back then. It continues to probe fine but needs to be rewritten
to use the special DSA tag and moved to drivers/net/dsa as time
permits. (I hope I can do this.)
It's fine for the networking tree to merge both patches, I maintain
ixp4xx as well. But I can also carry the second patch through the
SoC tree if so desired.

Fix up the KS8995 switch and PHYs the way that is most likely:
- Phy 1-4 is certainly the PHYs of the KS8995 (mask 0x1e in
the outoftree code masks PHYs 1,2,3,4).
- Phy 5 is the MII-P5 separate WAN phy of the KS8995 directly
connected to EthC.
- The EthB MII is probably connected as CPU interface to the
KS8995.
Properly integrate the KS8995 switch using the new bindings.

After studying the datasheets for some of the KS8995 variants
it becomes pretty obvious that this is a straight-forward
and simple MII DSA switch with one port in (CPU) and four outgoing
ports, and it even supports custom tags by setting a bit in
a special register, and elaborate VLAN handling as all DSA
switches do.
What is a bit odd with KS8995 is that it uses an extra MII-P5
port to access one of the PHYs separately, on the side of the
switch fabric, such as when using a WAN port separately from
a LAN switch in a home router.
Rewrite the terse bindings to YAML, and move to the proper
subdirectory. Include a verbose example to make things clear.

Add a device tree option to select RX gain reduction to improve EMC

Selecting a communication standard in the ISO control register resets
the RX antenna gain settings. Therefore set the RX gain reduction
everytime the ISO control register changes, when the option is used.
