This series overcomes existing hardware limitations in Mellanox ConnectX
devices around handling IPsec soft and hard limits.
In addition, the ESN logic is tied and added an interface to configure
replay window sequence numbers through existing iproute2 interface.

Any multiplication between GENMASK(31, 0) and a number bigger than 1
will be truncated because of the overflow, if the size of unsigned long
is 32 bits.
Replaced GENMASK with GENMASK_ULL to make sure that multiplication will
be between 64 bits values.

Add support for J784S4 CPSW9G
This series adds a new compatible to am65-cpsw driver for the CPSW9G
instance of the CPSW Ethernet Switch on TI's J784S4 SoC which has 8
external ports and 1 internal host port.
The CPSW9G instance supports QSGMII and USXGMII modes for which driver
support is added.
Additionally, the interface mode specific configurations are moved to the
am65_cpsw_nuss_mac_config() callback. Also, a TODO comment is added for
verifying whether in-band mode is necessary for 10 Mbps RGMII mode.
NOTE:
I have verified that the mac_config() operations are preserved across
link up and link down events for SGMII and USXGMII mode with the new
implementation in this series, as suggested by:
Russell King <linux@armlinux.org.uk>
For patches 1 and 3 of this series, I believe that the following tag:
Suggested-by: Russell King <linux@armlinux.org.uk>
should be added. However, I did not add it since I did not yet get
the permission to do so. I will be happy if the tags are added, since
the new implementation is almost entirely based on Russell's suggestion,
with minor changes made by me.

Move the interface mode specific configuration to the mac_config()
callback am65_cpsw_nuss_mac_config().
Also, do not reset the MAC Control register on mac_link_down(). Only
clear those bits that can possibly be set in mac_link_up().
Let the MAC remain in IDLE state after mac_link_down(). Bring it out of
the IDLE state on mac_link_up().

assume the following setup on a single machine:
1. An openvswitch instance with one bridge and default flows
2. two network namespaces "server" and "client"
3. two ovs interfaces "server" and "client" on the bridge
4. for each ovs interface a veth pair with a matching name and 32 rx and
tx queues
5. move the ends of the veth pairs to the respective network namespaces
6. assign ip addresses to each of the veth ends in the namespaces (needs
to be the same subnet)
7. start some http server on the server network namespace
8. test if a client in the client namespace can reach the http server
when following the actions below the host has a chance of getting a cpu
stuck in a infinite loop:
1. send a large amount of parallel requests to the http server (around
3000 curls should work)
2. in parallel delete the network namespace (do not delete interfaces or
stop the server, just kill the namespace)
there is a low chance that this will cause the below kernel cpu stuck
message. If this does not happen just retry.
Below there is also the output of bpftrace for the functions mentioned
in the output.
The series of events happening here is:
1. the network namespace is deleted calling
`unregister_netdevice_many_notify` somewhere in the process
2. this sets first `NETREG_UNREGISTERING` on both ends of the veth and
then runs `synchronize_net`
3. it then calls `call_netdevice_notifiers` with `NETDEV_UNREGISTER`
4. this is then handled by `dp_device_event` which calls
`ovs_netdev_detach_dev` (if a vport is found, which is the case for
the veth interface attached to ovs)
5. this removes the rx_handlers of the device but does not prevent
packages to be sent to the device
6. `dp_device_event` then queues the vport deletion to work in
background as a ovs_lock is needed that we do not hold in the
unregistration path
7. `unregister_netdevice_many_notify` continues to call
`netdev_unregister_kobject` which sets `real_num_tx_queues` to 0
8. port deletion continues (but details are not relevant for this issue)
9. at some future point the background task deletes the vport
If after 7. but before 9. a packet is send to the ovs vport (which is
not deleted at this point in time) which forwards it to the
`dev_queue_xmit` flow even though the device is unregistering.
In `skb_tx_hash` (which is called in the `dev_queue_xmit`) path there is
a while loop (if the packet has a rx_queue recorded) that is infinite if
`dev->real_num_tx_queues` is zero.
To prevent this from happening we update `do_output` to handle devices
without carrier the same as if the device is not found (which would
be the code path after 9. is done).
Additionally we now produce a warning in `skb_tx_hash` if we will hit
the infinite loop.

SM8150 has (at least) two GPU speed bins. With the support added on the
driver side, wire up bin detection in the DTS to restrict lower-quality
SKUs from running at frequencies they were not validated at.

Now that there's display support, there is no reason to assume the default
mode for Adreno should be headless. Keep it like that for boards that
previously enabled it, so as not to create regressions though.

When the SOC approaches zero, an integer overflows in the columb
counter causing the driver to react poorly. This makes the driver
think it's at (above) the fully charged capacity when in fact it's
zero. It would then write this full capacity to NVRAM which would be
used on boot if the device remained off for less than 5 hours and
not plugged in.
This can be fixed and guarded against by doing the following:
- Changing the type of tmp in rk817_read_or_set_full_charge_on_boot()
to be an int instead of a u32. That way we can account for negative
numbers.
- Guard against negative values for the full charge on boot by setting
the charge to 0 if the system charge reports less than 0.
- Catch scenarios where the battery voltage is below the design
minimum voltage and set the system SOC to 0 at that time and update
the columb counter with a charge level of 0.
- Change the off time value from 5 hours to 30 minutes before we
recalculate the current capacity based on the OCV tables.
These changes allow the driver to operate better at low voltage/low
capacity conditions.

During EDR recovery, the OS must clear error status of the port that
triggered DPC even if firmware retains control of DPC and AER (see the
implementation note in the PCI Firmware spec r3.3, sec 4.6.12).
Prior to 068c29a248 ("PCI/ERR: Clear PCIe Device Status errors only if
OS owns AER"), the port Device Status was cleared in this path:
edr_handle_event
dpc_process_error(dev) # "dev" triggered DPC
pcie_do_recovery(dev, dpc_reset_link)
dpc_reset_link # exit DPC
pcie_clear_device_status(dev) # clear Device Status
After 068c29a248, pcie_do_recovery() no longer clears Device Status when
firmware controls AER, so the error bit remains set even after recovery.
Per the "Downstream Port Containment configuration control" bit in the
returned _OSC Control Field (sec 4.5.1), the OS is allowed to clear error
status until it evaluates _OST, so clear Device Status in
edr_handle_event() if the error recovery was successful.

Merge tag '20230407105029.2274111-4-abel.vesa@linaro.org' into drivers-for-6.4
The dedicated ICE driver was merged through a immutable tag, to make it
available to other maintainers.
This takes the already existing duplicated support in both ufs-qcom
and sdhci-msm drivers and makes it a dedicated driver that can be used
by both mentioned drivers.
The reason for this is because, staring with SM8550, the ICE IP block
is shared between UFS and SDCC, which means we need to probe a dedicated
device and share it between those two consumers.
So let's add the ICE dedicated driver as a soc driver.
Platforms that already have ICE supported, will use it as a library
as the of_qcom_ice_get will return an ICE instance created for the
consumer device. This allows the backwards compatibility with old-style
devicetree approach.
Also, add support to HW version 4.x since it works out-of-the-box with
the current driver. The 4.x HW version is found on SM8550 platform.
