The iface field of struct gs_can is only used to retrieve the
usb_device which is already available in gs_can::udev.
Replace each occurrence of interface_to_usbdev(dev->iface) with
dev->udev. This done, remove gs_can::iface.

ES58x devices report below product information through a custom usb
string:
* the firmware version
* the bootloader version
* the hardware revision
Parse this string, store the results in struct es58x_dev, export:
* the firmware version through devlink's "fw" name
* the bootloader version through devlink's "fw.bootloader" name
* the hardware revisionthrough devlink's "board.rev" name
Those devlink entries are not critical to use the device, if parsing
fails, print an informative log message and continue to probe the
device.
In addition to that, use usb_device::serial to report the device
serial number.

IMX93 do not contain a GPR to config the stop mode, it will set
the flexcan into stop mode automatically once the ARM core go
into low power mode (WFI instruct) and gate off the flexcan
related clock automatically. But to let these logic work as
expect, before ARM core go into low power mode, need to make
sure the flexcan related clock keep on.
To support stop mode and wakeup feature on imx93, this patch
add a new fsl_imx93_devtype_data to separate from imx8mp.

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

The CAN FD IP found on RZ/G2L SoC has some HW features different to that
of R-Car. For example, it has multiple resets and multiple IRQs for global
and channel interrupts. Also, it does not have ECC error flag registers
and clk post divider present on R-Car. Similarly, R-Car V3U has 8 channels
whereas other SoCs has only 2 channels.
This patch adds the struct rcar_canfd_hw_info to take care of the
HW feature differences and driver data present on both IPs. It also
replaces the driver data chip type with struct rcar_canfd_hw_info by
moving chip type to it.
Whilst started using driver data instead of chip_id for detecting

mlx5-updates-2022-12-08
1) Support range match action in SW steering
Yevgeny Kliteynik says:
=======================
The following patch series adds support for a range match action in
SW Steering.
SW steering is able to match only on the exact values of the packet fields,
as requested by the user: the user provides mask for the fields that are of
interest, and the exact values to be matched on when the traffic is handled.
The following patch series add new type of action - Range Match, where the
user provides a field to be matched on and a range of values (min to max)
that will be considered as hit.
There are several new notions that were implemented in order to support
Range Match:
- MATCH_RANGES Steering Table Entry (STE): the new STE type that allows
matching the packets' fields on the range of values instead of a specific
value.
- Match Definer: this is a general FW object that defines which fields
in the packet will be referenced by the mask and tag of each STE.
Match definer ID is part of STE fields, and it defines how the HW needs
to interpret the STE's mask/tag values.
Till now SW steering used the definers that were managed by FW and
implemented the STE layout as described by the HW spec.
Now that we're adding a new type of STE, SW steering needs to also be
able to define this new STE's layout, and this is do

====================
Intel Wired LAN Driver Updates 2022-12-08 (ice)
Jacob Keller says:
This series of patches primarily consists of changes to fix some corner
cases that can cause Tx timestamp failures. The issues were discovered and
reported by Siddaraju DH and primarily affect E822 hardware, though this
series also includes some improvements that affect E810 hardware as well.
The primary issue is regarding the way that E822 determines when to generate
timestamp interrupts. If the driver reads timestamp indexes which do not
have a valid timestamp, the E822 interrupt tracking logic can get stuck.
This is due to the way that E822 hardware tracks timestamp index reads
internally. I was previously unaware of this behavior as it is significantly
different in E810 hardware.
Most of the fixes target refactors to ensure that the ice driver does not
read timestamp indexes which are not valid on E822 hardware. This is done by
using the Tx timestamp ready bitmap register from the PHY. This register
indicates what timestamp indexes have outstanding timestamps waiting to be
captured.
Care must be taken in all cases where we read the timestamp registers, and
thus all flows which might have read these registers are refactored. The
ice_ptp_tx_tstamp function is modified to consolidate as much of the logic
relating to these registers as possible. It now handles discarding stale
timestamps which are old or which occurred after a PHC time update. This
replaces previously standalone thread functions like the periodic work
function and the ice_ptp_flush_tx_tracker function.
In addition, some minor cleanups noticed while writing these refactors are
included.
The remaining patches refactor the E822 implementation to remove the
"bypass" mode for timestamps. The E822 hardware has the ability to provide a
more precise timestamp by making use of measurements of the precise way that
packets flow through the hardware pipeline. These measurements are known as
"Vernier" calibration. The "bypass" mode disables many of these measurements
in favor of a faster start up time for Tx and Rx timestamping. Instead, once
these measurements were captured, the driver tries to reconfigure the PHY to
enable the vernier calibrations.
Unfortunately this recalibration does not work. Testing indicates that the
PHY simply remains in bypass mode without the increased timestamp precision.
Remove the attempt at recalibration and always use vernier mode. This has
one disadvantage that Tx and Rx timestamps cannot begin until after at least
one packet of that type goes through the hardware pipeline. Because of this,
further refactor the driver to separate Tx and Rx vernier calibration.
Complete the Tx and Rx independently, enabling the appropriate type of
timestamp as soon as the relevant packet has traversed the hardware
pipeline. This was reported by Milena Olech.
Note that although these might be considered "bug fixes", the required
changes in order to appropriately resolve these issues is large. Thus it
does not feel suitable to send this series to net.

There are two main differences between Spectrum-1 and newer ASICs in
terms of IP-in-IP support:
1. In Spectrum-1, RIFs representing ip6gre tunnels require two entries
in the RIF table.
2. In Spectrum-2 and newer ASICs, packets ingress the underlay (during
encapsulation) and egress the underlay (during decapsulation) via a
special generic loopback RIF.
The first difference was handled in previous patches by adding the
'double_rif_entry' field to the Spectrum-1 operations structure of
ip6gre RIFs. The second difference is handled during RIF creation, by
only creating a generic loopback RIF in Spectrum-2 and newer ASICs.
Therefore, the ip6gre operations can be shared between Spectrum-1 and
newer ASIC in a similar fashion to how the ipgre operations are shared.
Rename the operations to not be Spectrum-2 specific and move them
earlier in the file so that they could later be used for Spectrum-1.

In Spectrum-1, loopback router interfaces (RIFs) used for IP-in-IP
encapsulation with an IPv6 underlay require two RIF entries and the RIF
index must be even.
Prepare for this change by extending the RIF parameters structure with a
'double_entry' field that indicates if the RIF being created requires
two RIF entries or not. Only set it for RIFs representing ip6gre tunnels
in Spectrum-1.

Currently, each router interface (RIF) consumes one entry in the RIFs
table. This is going to change in subsequent patches where some RIFs
will consume two table entries.
Prepare for this change by parametrizing the RIF allocation size. For
now, always pass '1'.

Currently, each router interface (RIF) consumes one entry in the RIFs
table and there are no alignment constraints. This is going to change in
subsequent patches where some RIFs will consume two table entries and
their indexes will need to be aligned to the allocation size (even).
Prepare for this change by converting the RIF index allocation to use
gen_pool with the 'gen_pool_first_fit_order_align' algorithm.
No Kconfig changes necessary as mlxsw already selects
'GENERIC_ALLOCATOR'.

Up until now miss address in all the STEs was used to connect miss lists
and to link the last STE in the list to end anchor.
Match range STE will require special handling because its miss address is
part of the 'action'. That is, range action has hit and miss addresses.
Since the range action is always the last action, need to make sure that
its miss address isn't overwritten by the end anchor.
Adding new function mlx5dr_ste_is_miss_addr_set() to answer the question
whether the STE's miss address has already been set as part of STE
initialization. Use a callback that always returns false right now. Once
match range is added, a different callback will be used for that STE type.

In many cases different actions will ask for the same definer format.
Instead of allocating new definer general object and running out of
definers, have an xarray of allocated definers and keep track of their
usage with refcounts: allocate a new definer only when there isn't
one with the same format already created, and destroy definer only
when its refcount runs down to zero.

This patch handles the following two changes w.r.t. is_fw_table function:
1. When SW steering is asked to create/destroy FW table, we allow for
creation/destruction of only termination tables. Rename mlx5_dr_is_fw_table
both to comply with the static function naming and to reflect that we're
actually checking for FW termination table.
2. When the action 'go to flow table' is created, the destination flow
table can be any FW table, not only termination table. Adding function
to check if the dest table is FW table. This function will also be used
by the later creation of range match action, so putting it the header file.

SW steering is able to match only on the exact values of the packet fields,
as requested by the user: the user provides mask for the fields that are of
interest, and the exact values to be matched on when the traffic is handled.
Match Definer is a general FW object that defines which fields in the
packet will be referenced by the mask and tag of each STE. Match definer ID
is part of STE fields, and it defines how the HW needs to interpret the STE's
mask/tag values.
Till now SW steering used the definers that were managed by FW and implemented
the STE layout as described by the HW spec. Now that we're adding a new type
of STE, SW steering needs to define for the HW how it should interpret this
new STE's layout.
This is done with a programmable match definer.
The programmable definer allows to selects which fields will be included in
the definer, and their layout: it has up to 9 DW selectors 8 Byte selectors.
Each selector indicates a DW/Byte worth of fields out of the table that
is defined by HW spec by referencing the offset of the required DW/Byte.
This patch adds dr_cmd function to create and destroy MATCH_DEFINER
general object.

Range is a new flow destination type which allows matching on
a range of values instead of matching on a specific value.
Range flow destination has the following fields:
- hit_ft: flow table to forward the traffic in case of hit
- miss_ft: flow table to forward the traffic in case of miss
- field: which packet characteristic to match on
- min: minimal value for the selected field
- max: maximal value for the selected field
Note:
- In order to match, the value in the packet should meet
the following criteria: min <= value < max
- Currently, the only supported field type is L2 packet length
