The absence of Precision Time Measurement support should not emit a
message, as it can be misleading in contexts where PTM is not required.
Remove the log message indicating the lack of PCIe PTM support.

Add support for a new steering format version that is implemented by
ConnectX-8.
Except for several differences, the STEv3 is identical to STEv2, so
for most callbacks STEv3 context struct will call STEv2 functions.

HWS has two types of APIs:
- Native: fastest and slimmest, async API.
The user of this API is required to manage rule handles memory,
and to poll for completion for each rule.
- BWC: backward compatible API, similar semantics to SWS API.
This layer is implemented above native API and it does all
the work for the user, so that it is easy to switch between
SWS and HWS.
Right now the existing users of HWS require only BWC API.
Therefore, in order to not waste resources, this patch disables
send queues allocation for native API.
If in the future support for faster HWS rule insertion will be required
(such as for Connection Tracking), native queues can be enabled.

Refactor fc_pool API to create generic fs_pool API, as HW steering has
more flow steering elements which can take advantage of the same pool of
bulks API. Change fs_counters code to use the fs_pool API.
Note, removed __counted_by from struct mlx5_fc_bulk as bulk_len is now
inner struct member. It will be added back once __counted_by can support

Currently mlx5_flow_destination includes counter_id which is assigned in
case we use flow counter on the flow steering rule. However, counter_id
is not enough data in case of using HW Steering. Thus, have mlx5_fc
object as part of mlx5_flow_destination instead of counter_id and assign
it where needed.
In case counter_id is received from user space, create a local counter
object to represent it.

New multi-host NICs provide each host with partial ports,
allowing each host to maintain its unique LAG configuration.
On these multi-host NICs, the 'native_port_num' capability
is no longer continuous on each host and can exceed the
'num_lag_ports' capability. Therefore, it is necessary to
skip the PFs with ldev->pf[i].dev == NULL when querying/modifying
the lag devices' information.
There is no need to check dev.native_port_num against ldev->ports.

The SKB_DROP_REASON_VXLAN_NO_REMOTE skb drop reason was introduced in
the specific context of vxlan. As it turns out, there are similar cases
when a packet needs to be dropped in other parts of the network stack,
such as the bridge module.
Rename SKB_DROP_REASON_VXLAN_NO_REMOTE and give it a more generic name,
so that it can be used in other parts of the network stack. This is not
a functional change, and the numeric value of the drop reason even
remains unchanged.

ENETC rev 4.1 supports large send offload (LSO), segmenting large TCP
and UDP transmit units into multiple Ethernet frames. To support LSO,
software needs to fill some auxiliary information in Tx BD, such as LSO
header length, frame length, LSO maximum segment size, etc.
At 1Gbps link rate, TCP segmentation was tested using iperf3, and the
CPU performance before and after applying the patch was compared through
the top command. It can be seen that LSO saves a significant amount of
CPU cycles compared to software TSO.

The max chained Tx BDs of latest ENETC (i.MX95 ENETC, rev 4.1) has been
increased to 63, but since the range of MAX_SKB_FRAGS is 17~45, so for
i.MX95 ENETC and later revision, it is better to set ENETC4_MAX_SKB_FRAGS
to MAX_SKB_FRAGS.
In addition, add max_frags in struct enetc_drvdata to indicate the max
chained BDs supported by device. Because the max number of chained BDs
supported by LS1028A and i.MX95 ENETC is different.

In addition to supporting Rx checksum offload, i.MX95 ENETC also supports
Tx checksum offload. The transmit checksum offload is implemented through
the Tx BD. To support Tx checksum offload, software needs to fill some
auxiliary information in Tx BD, such as IP version, IP header offset and
size, whether L4 is UDP or TCP, etc.
Same as Rx checksum offload, Tx checksum offload capability isn't defined
in register, so tx_csum bit is added to struct enetc_drvdata to indicate
whether the device supports Tx checksum offload.

Current implementation of stmmac_probe_config_dt() does not release the
OF node reference obtained by of_parse_phandle() in some error paths.
The problem is that some error paths call stmmac_remove_config_dt() to
clean up but others use and unwind ladder. These two types of error
handling have not kept in sync and have been a recurring source of bugs.
Re-write the error handling in stmmac_probe_config_dt() to use an unwind
ladder. Consequently, stmmac_remove_config_dt() is not needed anymore,
thus remove it.
This bug was found by an experimental verification tool that I am
developing.

The CSR dump support leverages the FBNIC_BOUNDS macro, which pads the end
condition for each section by adding an offset of 1. However, the RPC RAM
section, which is dumped differently from other sections, does not rely
on this macro and instead directly uses end boundary address. Hence,
subtracting 1 from the end address results in skipping a register.

Due to HW limitation, the three region of WQE buffer must be mapped
and set to HW in a fixed order: SQ buffer, SGE buffer, and RQ buffer.
Currently when one region is zero-hop while the other two are not,
the zero-hop region will not be mapped. This violate the limitation
above and leads to address error.

My tests run an allyesconfig build and it failed with the following errors:
LD [M] samples/kfifo/dma-example.ko
ld.lld: error: undefined symbol: nec7210_board_reset
ld.lld: error: undefined symbol: nec7210_read
ld.lld: error: undefined symbol: nec7210_write
It appears that some modules call the function nec7210_board_reset()
that is defined in nec7210.c. In an allyesconfig build, these other
modules are built in. But the file that holds nec7210_board_reset()
has:
obj-m += nec7210.o
Where that "-m" means it only gets built as a module. With the other
modules built in, they have no access to nec7210_board_reset() and the build
fails.
This isn't the only function. After fixing that one, I hit another:
ld.lld: error: undefined symbol: push_gpib_event
ld.lld: error: undefined symbol: gpib_match_device_path
Where push_gpib_event() was also used outside of the file it was defined
in, and that file too only was built as a module.
Since the directory that nec7210.c is only traversed when
CONFIG_GPIB_NEC7210 is set, and the directory with gpib_common.c is only
traversed when CONFIG_GPIB_COMMON is set, use those configs as the
option to build those modules. When it is an allyesconfig, then they
will both be built in and their functions will be available to the other
modules that are also built in.

Pull PCI fixes from Krzysztof Wilczyński:
"Two small patches that are important for fixing boot time hang on
Intel JHL7540 'Titan Ridge' platforms equipped with a Thunderbolt
controller.
The boot time issue manifests itself when a PCI Express bandwidth
control is unnecessarily enabled on the Thunderbolt controller
downstream ports, which only supports a link speed of 2.5 GT/s in
accordance with USB4 v2 specification (p. 671, sec. 11.2.1, "PCIe
Physical Layer Logical Sub-block").
As such, there is no need to enable bandwidth control on such
downstream port links, which also works around the issue.
Both patches were tested by the original reporter on the hardware on
which the failure origin golly manifested itself. Both fixes were
proven to resolve the reported boot hang issue, and both patches have
been in linux-next this week with no reported problems"

These platform won't receive updated bootloader/firmware, so add an
exclusion for platforms with a "coreboot" compatible node. While this is
wider than necessary, that's the easiest fix and it doesn't doesn't
matter if we miss checking other platforms using coreboot.
We may revisit this later and address with a fixup to the DT itself.

The PTP driver code only works for certain KSZ switches like KSZ9477,
KSZ9567, LAN937X and their varieties. This code is enabled by kernel
configuration CONFIG_NET_DSA_MICROCHIP_KSZ_PTP. As the DSA driver is
common to work with all KSZ switches this PTP code is not appropriate
for other unsupported switches. The ptp_capable indication is added to
the chip data structure to signal whether to execute those code.
