====================
ethtool: Add ability to control transceiver modules' power mode
This patchset extends the ethtool netlink API to allow user space to
control transceiver modules. Two specific APIs are added, but the plan
is to extend the interface with more APIs in the future (see "Future
plans").
This submission is a complete rework of a previous submission [1] that
tried to achieve the same goal by allowing user space to write to the
EEPROMs of these modules. It was rejected as it could have enabled user
space binary blob drivers.
However, the main issue is that by directly writing to some pages of
these EEPROMs, we are interfering with the entity that is controlling
the modules (kernel / device firmware). In addition, some functionality
cannot be implemented solely by writing to the EEPROM, as it requires
the assertion / de-assertion of hardware signals (e.g., "ResetL" pin in
SFF-8636).
Motivation
==========
The kernel can currently dump the contents of module EEPROMs to user
space via the ethtool legacy ioctl API or the new netlink API. These
dumps can then be parsed by ethtool(8) according to the specification
that defines the memory map of the EEPROM. For example, SFF-8636 [2] for
QSFP and CMIS [3] for QSFP-DD.
In addition to read-only elements, these specifications also define
writeable elements that can be used to control the behavior of the
module. For example, controlling whether the module is put in low or
high power mode to limit its power consumption.
The CMIS specification even defines a message exchange mechanism (CDB,
Command Data Block) on top of the module's memory map. This allows the
host to send various commands to the module. For example, to update its
firmware.
Implementation
==============
The ethtool netlink API is extended with two new messages,
'ETHTOOL_MSG_MODULE_SET' and 'ETHTOOL_MSG_MODULE_GET', that allow user
space to set and get transceiver module parameters. Specifically, the
'ETHTOOL_A_MODULE_POWER_MODE_POLICY' attribute allows user space to
control the power mode policy of the module in order to limit its power
consumption. See detailed description in patch #1.
The user API is designed to be generic enough so that it could be used
for modules with different memory maps (e.g., SFF-8636, CMIS).
The only implementation of the device driver API in this series is for a
MAC driver (mlxsw) where the module is controlled by the device's
firmware, but it is designed to be generic enough so that it could also
be used by implementations where the module is controlled by the kernel.
Testing and introspection
=========================
See detailed description in patches #1 and #5.
Patchset overview
=================
Patch #1 adds the initial infrastructure in ethtool along with the
ability to control transceiver modules' power mode.
Patches #2-#3 add required device registers in mlxsw.
Patch #4 implements in mlxsw the ethtool operations added in patch #1.
Patch #5 adds extended link states in order to allow user space to
troubleshoot link down issues related to transceiver modules.
Patch #6 adds support for these extended states in mlxsw.
Future plans
============
* Extend 'ETHTOOL_MSG_MODULE_SET' to control Tx output among other
attributes.
* Add new ethtool message(s) to update firmware on transceiver modules.
* Extend ethtool(8) to parse more diagnostic information from CMIS
modules. No kernel changes required.

mlxsw: Add ability to control transceiver modules' power mode
Implement support for ethtool_ops::.get_module_power_mode and
ethtool_ops::set_module_power_mode.
The get operation is implemented using the Management Cable IO and
Notifications (MCION) register that reports the operational power mode
of the module and its presence. In case a module is not present, its
operational power mode is not reported to ethtool and user space. If not
set before, the power mode policy is reported as "high", which is the
default on Mellanox systems.
The set operation is implemented using the Port Module Memory Map
Properties (PMMP) register. The register instructs the device's firmware
to transition a plugged-in module to / out of low power mode by writing
to its memory map.
When the power mode policy is set to 'auto', a module will not
transition to low power mode as long as any ports using it are
administratively up. Example:
# devlink port split swp11 count 4
# ethtool --set-module swp11s0 power-mode-policy auto
$ ethtool --show-module swp11s0
Module parameters for swp11s0:

ethtool: Add ability to control transceiver modules' power mode
Add a pair of new ethtool messages, 'ETHTOOL_MSG_MODULE_SET' and
'ETHTOOL_MSG_MODULE_GET', that can be used to control transceiver
modules parameters and retrieve their status.
The first parameter to control is the power mode of the module. It is
only relevant for paged memory modules, as flat memory modules always
operate in low power mode.
When a paged memory module is in low power mode, its power consumption
is reduced to the minimum, the management interface towards the host is
available and the data path is deactivated.
User space can choose to put modules that are not currently in use in
low power mode and transition them to high power mode before putting the
associated ports administratively up. This is useful for user space that
favors reduced power consumption and lower temperatures over reduced
link up times. In QSFP-DD modules the transition from low power mode to
high power mode can take a few seconds and this transition is only
expected to get longer with future / more complex modules.
User space can control the power mode of the module via the power mode
policy attribute ('ETHTOOL_A_MODULE_POWER_MODE_POLICY'). Possible
values:
* high: Module is always in high power mode.
* auto: Module is transitioned by the host to high power mode when the
first port using it is put administratively up and to low power mode
when the last port using it is put administratively down.
The operational power mode of the module is available to user space via
the 'ETHTOOL_A_MODULE_POWER_MODE' attribute. The attribute is not
reported to user space when a module is not plugged-in.
The user API is designed to be generic enough so that it could be used
for modules with different memory maps (e.g., SFF-8636, CMIS).
The only implementation of the device driver API in this series is for a
MAC driver (mlxsw) where the module is controlled by the device's
firmware, but it is designed to be generic enough so that it could also
be used by implementations where the module is controlled by the CPU.

====================
RTL8366RB enhancements
This patch set is a set of reasonably mature improvements
for the RTL8366RB switch, implemented after Vladimir
challenged me to dig deeper into the switch functions.
ChangeLog v4->v5:
- Drop dubious flood control patch: these registers probably
only deal with rate limiting, we will deal with this
another time if we can figure it out.
ChangeLog -> v4:
- Rebase earlier circulated patches on the now merged
VLAN set-up cleanups.

Since the RTL8366RB has one STP state register per FID with

Misc updates for mlx5 driver

2) Trivial TC action and modify header refactoring
3) TC support for accept action in fdb offloads
4) Allow single IRQ for PCI functions
5) Bridge offload: Pop PVID VLAN header on egress miss
Vlad Buslov says:
=================
With current architecture of mlx5 bridge offload it is possible for a
packet to match in ingress table by source MAC (resulting VLAN header push
in case of port with configured PVID) and then miss in egress table when
destination MAC is not in FDB. Due to the lack of hardware learning in
NICs, this, in turn, results packet going to software data path with PVID
VLAN already added by hardware. This doesn't break software bridge since it
accepts either untagged packets or packets with any provisioned VLAN on
ports with PVID, but can break ingress TC, if affected part of Ethernet
header is matched by classifier.
Improve compatibility with software TC by restoring the packet header on
egress miss. Effectively, this change implements atomicity of mlx5 bridge
offload implementation - packet is either modified and redirected to
destination port or appears unmodified in software.

qed drivers (fastlinq devices). This FW does not reside in the NVRAM.
It needs to be programmed to device during driver load as the part of
initialization sequence.
Similar to previous FW support series, this FW is tightly linked to
software and pf function driver. This means FW release is not backward
compatible, and driver should always run with the FW it was designed
against.
FW binary blob is already submitted & accepted in linux-firmware repo.
Patches in the series include:
patch 1 - qed: Fix kernel-doc warnings
patch 2 - qed: Remove e4_ and _e4 from FW HSI
patch 3 - qed: split huge qed_hsi.h header file
patch 4-8 - HSI (hardware software interface) changes
patch 9 - qed: Add '_GTT' suffix to the IRO RAM macros
patch 10 - qed: Update debug related changes
patch 11 - qed: rdma: Update TCP silly-window-syndrome timeout
patch 12 - qed: Update the TCP active termination 2 MSL timer
patch 13 - qed: fix ll2 establishment during load of RDMA driver
In addition, this patch series also fixes existing checkpatch warnings
and checks which are missing.
Changes for v2:
- Incorporated Jakub's comments.
- New patch introduced to fix all kernel-doc issue in qed driver.
- Fixed warning: ‘qed_mfw_ext_20g’ defined but not used.
- Fixed warning related to kernel-doc wrt to this series.
- Removed inline function declaration.

Merge branch 'ipv6-ioam-encap'
Justin Iurman says:
====================
Support for the ip6ip6 encapsulation of IOAM
v2:
- add prerequisite patches
- keep uapi backwards compatible by adding two new attributes
- add more comments to document the ioam6_iptunnel uapi
In the current implementation, IOAM can only be inserted directly (i.e., only
inside packets generated locally) by default, to be compliant with RFC8200.
This patch adds support for in-transit packets and provides the ip6ip6
encapsulation of IOAM (RFC8200 compliant). Therefore, three ioam6 encap modes
are defined:
- inline: directly inserts IOAM inside packets (by default).
- encap: ip6ip6 encapsulation of IOAM inside packets.
- auto: either inline mode for packets generated locally or encap mode for
in-transit packets.
With current iproute2 implementation, it is configured this way:
$ ip -6 r [...] encap ioam6 trace prealloc [...]
The old syntax does not change (for backwards compatibility) and implicitly uses
the inline mode. With the new syntax, an encap mode can be specified:
(inline mode)
$ ip -6 r [...] encap ioam6 mode inline trace prealloc [...]
(encap mode)
$ ip -6 r [...] encap ioam6 mode encap tundst fc00::2 trace prealloc [...]
(auto mode)
$ ip -6 r [...] encap ioam6 mode auto tundst fc00::2 trace prealloc [...]
A tunnel destination address must be configured when using the encap mode or the
auto mode.

Input case: happens before ip6_forward, the IPv6 hop-limit is not decremented

decremented -> keep the same value for the IOAM hop-limit.
