net/mlx5: Create TC-miss priority and table
In order to adhere to kernel software datapath model bridge offloads must
come after TC and NF FDBs. Following patches in this series add new FDB
priority for bridge after FDB_FT_OFFLOAD. However, since netfilter offload
is implemented with unmanaged tables, its miss path is not automatically
connected to next priority and requires the code to manually connect with
slow table. To keep bridge offloads encapsulated and not mix it with
eswitch offloads, create a new FDB_TC_MISS priority between FDB_FT_OFFLOAD
and FDB_SLOW_PATH:
+
|
+---------v----------+
| |
| FDB_TC_OFFLOAD |
| |
+---------+----------+
|
|
|
+---------v----------+
| |
| FDB_FT_OFFLOAD |
| |
+---------+----------+
|
|
|
+---------v----------+
| |
| FDB_TC_MISS |
| |
+---------+----------+
|
|
|
+---------v----------+
| |
| FDB_SLOW_PATH |
| |
+---------+----------+
|
v
Initialize the new priority with single default empty managed table and use
the table as TC/NF miss patch instead of slow table. This approach allows
bridge offloads to be created as new FDB namespace priority between
FDB_TC_MISS and FDB_SLOW_PATH without exposing its internal tables to any
other modules since miss path of managed TC-miss table is automatically
wired to next priority.

====================
net: ipa: memory region rework, part 1
This is the first portion of a very long series of patches that has
been split in two. Once these patches are accepted, I'll post the
remaining patches.
The combined series reworks the way memory regions are defined in
the configuration data, and in the process solidifies code that
ensures configurations are valid.
In this portion (part 1), most of the focus is on improving
validation of code. This validation is now done unconditionally
(something I promised Leon Romanovsky I would work on). Validation
will occur earlier than before, catching configuration problems as
early as possible and permitting the rest of the driver to avoid
needing to do some error checking. There will now be checks to
ensure all defined regions are supported by the hardware, that
required regions are all defined, and that there are no duplicate
regions.
The second portion (part 2) is mainly a set of small but pervasive
changes whose result is to have the memory region array not be
indexed by region ID. I'll provide further explanation when I post
that series.

netdevsim: delete unnecessary debugfs checking
In normal situations where the driver doesn't dereference
"nsim_node->ddir" or "nsim_node->rate_parent" itself then we are not
supposed to check the return from debugfs functions. In the case of
debugfs_create_dir() the check was wrong as well because it doesn't
return NULL, it returns error pointers.

Commit
ca8931948344 ("net: dsa: b53: Keep CPU port as tagged in all
VLANs") forced the CPU port to be always tagged in any VLAN membership.
This was necessary back then because we did not support Broadcom tags
for all configurations so the only way to differentiate tagged and
untagged traffic while DSA_TAG_PROTO_NONE was used was to force the CPU
port into being always tagged.
With most configurations enabling Broadcom tags, especially after
8fab459e69ab ("net: dsa: b53: Enable Broadcom tags for 531x5/539x
families") we do not need to apply this unconditional force tagging of
the CPU port in all VLANs.
A helper function is introduced to faciliate the encapsulation of the
specific condition requiring the CPU port to be tagged in all VLANs and
the dsa_switch_ops::untag_bridge_pvid boolean is moved to when
dsa_switch_ops::setup is called when we have already determined the
tagging protocol we will be using.

This tweaks several small places to improve the data access in fast
path:
* Remove duplicates of first_interrupt flag and surround it with
WRITE/READ_ONCE macros:
The flag is used to detect HW disorders in its
interrupt communication with the driver. The flag is set when an
interrupt is received and used in the health check function
(ena_timer_service()) to help it find irregularities.
* Reorder some fields in ena_napi struct to take better advantage of
cache access pattern.
* Move XDP TX queue number to a variable to save its calculation for
every packet.
* Use likely in a condition to improve branch prediction
The 'first_interrupt' and 'interrupt_masked' flags were moved to reside
in the same cache line as the first fields of 'napi' struct. This
placement ensures that all memory accessed during upper-half handler
reside in the same cacheline (napi_schedule_irqoff() only accesses
'state' and 'poll_list' fields which are at the beginning of napi
struct).

====================
mlxsw: Various updates
This patchset contains various updates for mlxsw. The most significant
change is the long overdue removal of the abort mechanism in the first
two patches.
Patches #1-#2 remove the route abort mechanism. This change is long
overdue and explained in detail in the commit message.
Patch #3 sets ports down in a few selftests that forgot to do so.
Discovered using a BPF tool (WIP) that monitors ASIC resources.
Patch #4 fixes an issue introduced by commit
557c4d2f780c ("selftests:
devlink_lib: add check for devlink device existence").
Patches #5-#8 modify the driver to read transceiver module's temperature
thresholds using MTMP register (when supported) instead of directly from
the module's EEPROM using MCIA register. This is both more reliable and
more efficient as now the module's temperature and thresholds are read
using one transaction instead of three.

selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEV
In the commit referenced below, a check was added to devlink_lib that
asserts the existence of a devlink device referenced by $DEVLINK_DEV.
Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that
does not exist at the time that devlink_lib is sourced. Thus these tests
spuriously fail.
Fix this by introducing an override. By setting DEVLINK_DEV to an empty
string, the user declares their intention to handle DEVLINK_DEV management
on their own.
In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set
instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it
to the correct value right afterwards.

mlxsw: spectrum_router: Remove abort mechanism
The abort mechanism was introduced in commit
8e05fd7166c6 ("fib: hook
IPv4 fib for hardware offload") with the purpose of falling back to
software-based routing in case of a route programming error in hardware.
The process is irreversible and requires users to reload the offloading
driver or reboot the machine.
While this approach might make sense in theory, it makes very little
sense in practice. In the case of high speed ASICs such as the Spectrum
ASIC, the abort mechanism effectively kills the machine upon a non-fatal
error such as a route programming error.
Such an extreme policy does not belong in the kernel, especially when
user space can simply try to reprogram the route following the
RTM_NEWROUTE failure notification.
Therefore, remove the abort mechanism.

Vladimir Oltean says:
====================
Add NXP SJA1110 support to the sja1105 DSA driver
The NXP SJA1110 is an automotive Ethernet switch with an embedded Arm
Cortex-M7 microcontroller. The switch has 11 ports (10 external + one
for the DSA-style connection to the microcontroller).
The microcontroller can be disabled and the switch can be controlled
over SPI, a la SJA1105 - this is how this driver handles things.
There are some integrated NXP PHYs (100base-T1 and 100base-TX). Their
initialization is handled by their own PHY drivers, the switch is only
concerned with enabling register accesses to them, by registering two
MDIO buses.
Changes in v3:
- Make sure the VLAN retagging port is enabled and functional
- Dropped SGMII PCS from this series
Changes in v2:
- converted nxp,sja1105 DT bindings to YAML
- registered the PCS MDIO bus and forced auto-probing off for all PHY
addresses for this bus
- changed the container node name for the 2 MDIO buses from "mdio" to
"mdios" to avoid matching on the mdio.yaml schema (it's just a
container node, not an MDIO bus)
- fixed an uninitialized "offset" variable usage in
sja1110_pcs_mdio_{read,write}
- using the mdiobus_c45_addr macro instead of open-coding that operation
