====================
bnxt devlink support
====================

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

Parameters
==========

.. list-table:: Generic parameters implemented

   * - Name
     - Mode
   * - ``enable_sriov``
     - Permanent
   * - ``ignore_ari``
     - Permanent
   * - ``msix_vec_per_pf_max``
     - Permanent
   * - ``msix_vec_per_pf_min``
     - Permanent
   * - ``enable_remote_dev_reset``
     - Runtime
   * - ``enable_roce``
     - Permanent

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

   * - Name
     - Type
     - Mode
     - Description
   * - ``gre_ver_check``
     - Boolean
     - Permanent
     - Generic Routing Encapsulation (GRE) version check will be enabled in
       the device. If disabled, the device will skip the version check for
       incoming packets.

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

The ``bnxt_en`` driver reports the following versions

   * - Name
     - Type
     - Description
   * - ``board.id``
     - fixed
     - Part number identifying the board design
   * - ``asic.id``
     - fixed
     - ASIC design identifier
   * - ``asic.rev``
     - fixed
     - ASIC design revision
   * - ``fw.psid``
     - stored, running
     - Firmware parameter set version of the board
   * - ``fw``

Annotation

Atlas domain: Support Tooling And Documentation / Documentation.
Implementation status: atlas-only.
IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
