Merge branch 'ethtool-add-ability-to-control-transceiver-modules-power-mode'

Ido Schimmel says:

====================
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.

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.
