Add interface to support Power Sourcing Equipment. At current step it
provides generic way to address all variants of PSE devices as defined
in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4
PoDL Power Sourcing Equipment (PSE).
Currently supported and mandatory objects are:
IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus
IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState
IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl
This is minimal interface needed to control PSE on each separate
ethernet port but it provides not all mandatory objects specified in
IEEE 802.3-2018.
Since "PoDL PSE" and "PSE" have similar names, but some different values
I decide to not merge them and keep separate naming schema. This should
allow as to be as close to IEEE 802.3 spec as possible and avoid name
conflicts in the future.
This implementation is connected to PHYs instead of MACs because PSE
auto classification can potentially interfere with PHY auto negotiation.
So, may be some extra PHY related initialization will be needed.
With WIP version of ethtools interaction with PSE capable link looks
as following:
$ ip l
...
5: t1l1@eth0: <BROADCAST,MULTICAST> ..
...
$ ethtool --show-pse t1l1

PoDL PSE Admin State: disabled
PoDL PSE Power Detection Status: disabled
$ ethtool --set-pse t1l1 podl-pse-admin-control enable
$ ethtool --show-pse t1l1

We poll nexthops in HW and call for each active nexthop appropriate
neighbour.
Also we provide implicity neighbour resolving.
For example, user have added nexthop route:
# ip route add 5.5.5.5 via 1.1.1.2
But neighbour 1.1.1.2 doesn't exist. In this case we will try to call
neigh_event_send, even if there is no traffic.
This is useful, when you have add route, which will be used after some
time but with a lot of traffic (burst). So, we has prepared, offloaded
route in advance.

When XSK frame size is 3072 (or another power of two multiplied by 3),
KLM mechanism for NIC virtual memory page mapping can be optimized by
replacing it with KSM.
Before this change, two KLM entries were needed to map an XSK frame that
is not a power of two: one entry maps the UMEM memory up to the frame
length, the other maps the rest of the stride to the garbage page.
When the frame length divided by 3 is a power of two, it can be mapped
using 3 KSM entries, and the fourth will map the rest of the stride to
the garbage page. All 4 KSM entries are of the same size, which allows
for a much faster lookup.
Frame size 3072 is useful in certain use cases, because it allows
packing 4 frames into 3 pages. Generally speaking, other frame sizes
equal to PAGE_SIZE minus a power of two can be optimized in a similar
way, but it will require many more KSMs per frame, which slows down UMRs
a little bit, but more importantly may hit the limit for the maximum
number of KSM entries.

On striding RQ, when the XSK frame size doesn't match the MKey page
size, KLM is used for memory mappings, which is a slower mechanism than
MTT or KSM. It may happen in two cases:
1. Frame size is not a power of two (only possible in the unaligned mode
of XSK).
2. Frame size is 2048 bytes, and the firmware doesn't support MKey pages
smaller than 4096 bytes.
Depending on the case, print a warning and recommend to disable striding
RQ or upgrade the firmware.

XSK RQs support striding RQ linear mode, but the stride size may be
bigger than the XSK frame size, because:
1. The stride size must be a power of two.
2. The stride size must be equal to the UMR page size. Each XSK frame is
treated as a separate page, because they aren't necessarily adjacent in
physical memory, so the driver can't put more than one stride per page.
3. The minimal MTT page size is 4096 on older firmware.
That means that if XSK frame size is 2048 or not a power of two, the
strides may be bigger than XSK frames. Normally, it's not a problem if
the hardware enforces the MTU. However, traffic between vports skips the
hardware MTU check, and oversized packets may be received.
If an oversized packet is bigger than the XSK frame but not bigger than
the stride, it will cause overwriting of the adjacent UMEM region. If
the packet takes more than one stride, they can be recycled for reuse,
so it's not a problem when the XSK frame size matches the stride size.
Work around the above issue by leveraging KLM to make a more
fine-grained mapping. The beginning of each stride is mapped to the
frame memory, and the padding up to the closest power of two is mapped
to the overflow page that doesn't belong to UMEM. This way, application
data corruption won't happen upon receiving packets bigger than MTU.

Make mlx5e_mpwrq_mtts_per_wqe take into account that KSM requires
smaller alignment than MTT.
Ensure that there is always an even amount of MTTs in a UMR WQE, so that
complete octwords are formed, and no garbage is mapped.
Drop extra alignment in MLX5_MTT_OCTW that may cause setting too big
ucseg->xlt_octowords, also leading to mapping garbage.

XSK need_wakeup mechanism allows the driver to stop busy waiting for
buffers when the fill ring is empty, yield to the application and signal
it that the driver needs to be waken up after the application refills
the fill ring.
Add protection against the race condition on the RX (refill) side: if
the application refills buffers after xskrq->post_wqes is called, but
before mlx5e_xsk_update_rx_wakeup, NAPI will exit, skipping taking these
buffers to the hardware WQ, and the application won't wake it up again.

compensate for this new check.

When mvpp2 is unloaded, the driver specific debugfs directory is not
removed, which technically leads to a memory leak. However, this
directory is only created when the first device is probed, so the
hardware is present. Removing the module is only something a developer
would to when e.g. testing out changes, so the module would be
reloaded. So this memory leak is minor.
The original attempt in commit fe2c9c61f668 ("net: mvpp2: debugfs: fix
memory leak when using debugfs_lookup()") that was labelled as a memory
leak fix was not, it fixed a refcount leak, but in doing so created a
problem when the module is reloaded - the directory already exists, but
mvpp2_root is NULL, so we lose all debugfs entries. This fix has been
reverted.
This is the alternative fix, where we remove the offending directory
whenever the driver is unloaded.

This patch just updates comments throughout the IPA code.
Transaction state is now tracked using indexes into an array rather
than linked lists, and a few comments refer to the "old way" of
doing things. The description of how transactions are used was
changed to refer to "operations" rather than "commands", to
(hopefully) remove a possible ambiguity.
IPA register offsets and fields are now handled differently as well,
and the register documentation is updated to better describe the
code.
A few minor updates to comments were made (e.g., adding a missing
word, fixing a typo or punctuation, etc.).
Finally, the local macro atomic_dec_not_zero() is no longer used, so

Merge core thermal control changes for 6.1-rc1:
- Increase maximum number of trip points in the thermal core (Sumeet
Pawnikar).
- Replace strlcpy() with unused retval with strscpy() in the core
thermal control code (Wolfram Sang).
- Do not lock thermal zone mutex in the user space governor (Rafael
Wysocki)
- Rework the device tree initialization, convert the drivers to the
new API and remove the old OF code (Daniel Lezcano)
- Fix return value to -ENODEV when searching for a specific thermal
zone which does not exist (Daniel Lezcano)
- Fix the return value inspection in of_thermal_zone_find() (Dan
Carpenter)
- Fix kernel panic when KASAN is enabled as it detects use after
free when unregistering a thermal zone (Daniel Lezcano)
- Move the set_trip ops inside the therma sysfs code (Daniel Lezcano)
- Remove unnecessary error message as it is already showed in the
underlying function (Jiapeng Chong)
- Rework the monitoring path and move the locks upper in the call
stack to fix some potentials race windows (Daniel Lezcano)
- Fix lockdep_assert() warning introduced by the lock rework (Daniel
Lezcano)
- Revert the Mellanox 'hotter thermal zone' feature because it is
already handled in the thermal framework core code (Daniel Lezcano)

wwan_register_ops calls wwan_create_default_link, which ends up in the
ipc_wwan_newlink callback that locks ipc_wwan->if_mutex. However, this
mutex is not yet initialized by that point. Fix it by moving mutex_init
above the wwan_register_ops call. This also makes the order of
operations in ipc_wwan_init symmetric to ipc_wwan_deinit.

This patch introduces the macsec offload feature to cn10k
PF netdev driver. The macsec offload ops like adding, deleting
and updating SecYs, SCs, SAs and stats are supported. XPN support
will be added in later patches. Some stats use same counter in hardware
which means based on the SecY mode the same counter represents different
stat. Hence when SecY mode/policy is changed then snapshot of current
stats are captured. Also there is no provision to specify the unique
flow-id/SCI per packet to hardware hence different mac address needs to
be set for macsec interfaces.

Hardware triggers an interrupt for events like PN wrap to zero,
PN crosses set threshold. This interrupt is received
by the MCS_AF. MCS AF then finds the PF/VF to which SA is mapped
and notifies them using mcs_intr_notify mbox message.
PF/VF using mcs_intr_cfg mbox can configure the list
of interrupts for which they want to receive the
notification from AF.

Out of all the TCAM entries, reserve last TX and RX TCAM flow
entry(low priority) so that normal traffic can be sent out and
received. The traffic which needs macsec processing hits the
high priority TCAM flows. Also install a FLR handler to free
the allocated resources for PF/VF.

To establish a macsec connection association netdev driver
needs hardware resources like SecY, TCAM flows, SCs and SAs.
This patch manages allocating, freeing and configuring those
resources. AF consumers can request resources and configure them
via these mailbox messages. AF can allocate until it runs out of
hardware resources.

CN10K-B and CNF10K-B has macsec block(MCS) to encrypt and
decrypt packets at MAC level. This block is a global resource
with hardware resources like SecYs, SCs and SAs and is in
between NIX block and RPM LMAC. CN10K-B silicon has only one MCS
block which receives packets from all LMACS whereas CNF10K-B has
seven MCS blocks for seven LMACs. Both MCS blocks are
similar in operation except for few register offsets and some
configurations require writing to different registers. Those
differences between IPs are handled using separate ops.
This patch adds basic driver and does the initial hardware
calibration and parser configuration.

at a time and it is possible to have both ingress and egress mirroring.
Frames injected by the CPU don't get egress mirrored because they are
