mlxsw devlink support
=====================

This document describes the devlink features implemented by the ``mlxsw``
device driver.

Parameters
==========

.. list-table:: Generic parameters implemented

   * - Name
     - Mode
   * - ``fw_load_policy``
     - driverinit

The ``mlxsw`` driver also implements the following driver-specific
parameters.

.. list-table:: Driver-specific parameters implemented
   :widths: 5 5 5 85

   * - Name
     - Type
     - Mode
     - Description
   * - ``acl_region_rehash_interval``
     - u32
     - runtime
     - Sets an interval for periodic ACL region rehashes. The value is
       specified in milliseconds, with a minimum of ``3000``. The value of
       ``0`` disables periodic work entirely. The first rehash will be run
       immediately after the value is set.

The ``mlxsw`` driver supports reloading via ``DEVLINK_CMD_RELOAD``

Info versions
=============

The ``mlxsw`` driver reports the following versions

.. list-table:: devlink info versions implemented
   :widths: 5 5 90

   * - Name
     - Type
     - Description
   * - ``hw.revision``
     - fixed
     - The hardware revision for this board
   * - ``fw.psid``
     - fixed
     - Firmware PSID
   * - ``fw.version``
     - running
     - Three digit firmware version

Line card auxiliary device info versions
========================================

The ``mlxsw`` driver reports the following versions for line card auxiliary device

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
