+
+``devlink`` provides capability for a driver to expose device parameters for low
+level device functionality. Since devlink can operate at the device-wide
+level, it can be used to provide configuration that may affect multiple
+ports on a single device.
+
+This document describes a number of generic parameters that are supported
+across multiple drivers. Each driver is also free to add their own
+parameters. Each driver must document the specific parameters they support,
+whether generic or not.
+
+Configuration modes
+===================
+
+Parameters may be set in different configuration modes.

+     - set while the driver is running, and takes effect immediately. No
+       reset is required.
+   * - ``driverinit``
+     - applied while the driver initializes. Requires the user to restart
+       the driver using the ``devlink`` reload command.
+   * - ``permanent``
+     - written to the device's non-volatile memory. A hard reset is required
+       for it to take effect.

+Generic configuration parameters
+================================
+The following is a list of generic configuration parameters that drivers may

+     - Enable Single Root I/O Virtualization (SRIOV) in the device.
+   * - ``ignore_ari``
+     - Boolean
+     - Ignore Alternative Routing-ID Interpretation (ARI) capability. If
+       enabled, the adapter will ignore ARI capability even when the

-Devlink configuration parameters
-================================
-Following is the list of configuration parameters via devlink interface.
-Each parameter can be generic or driver specific and are device level
-parameters.
-
-Note that the driver-specific files should contain the generic params
-they support to, with supported config modes.
-
-Each parameter can be set in different configuration modes:
-	runtime		- set while driver is running, no reset required.
-	driverinit	- applied while driver initializes, requires restart
-			driver by devlink reload command.
-	permanent	- written to device's non-volatile memory, hard reset
-			required.
-
-Following is the list of parameters:
-====================================
-enable_sriov		[DEVICE, GENERIC]
-			Enable Single Root I/O Virtualisation (SRIOV) in
-			the device.
-			Type: Boolean
-
-ignore_ari		[DEVICE, GENERIC]
-			Ignore Alternative Routing-ID Interpretation (ARI)

-			capability even when platforms has the support
-			enabled and creates same number of partitions when
-			platform does not support ARI.
-			Type: Boolean
-
-msix_vec_per_pf_max	[DEVICE, GENERIC]
-			Provides the maximum number of MSIX interrupts that
-			a device can create. Value is same across all

-			Type: u32
-
-msix_vec_per_pf_min	[DEVICE, GENERIC]
-			Provides the minimum number of MSIX interrupts required
-			for the device initialization. Value is same across all
-			physical functions (PFs) in the device.
-			Type: u32
-
-fw_load_policy		[DEVICE, GENERIC]
-			Controls the device's firmware loading policy.
-			Valid values:
-			* DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_DRIVER (0)
-			  Load firmware version preferred by the driver.
-			* DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_FLASH (1)
-			  Load firmware currently stored in flash.
-			* DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_DISK (2)
-			  Load firmware currently available on host's disk.
-			Type: u8
-
-reset_dev_on_drv_probe	[DEVICE, GENERIC]
-			Controls the device's reset policy on driver probe.
-			Valid values:
-			* DEVLINK_PARAM_RESET_DEV_ON_DRV_PROBE_VALUE_UNKNOWN (0)
-			  Unknown or invalid value.
-			* DEVLINK_PARAM_RESET_DEV_ON_DRV_PROBE_VALUE_ALWAYS (1)
-			  Always reset device on driver probe.
-			* DEVLINK_PARAM_RESET_DEV_ON_DRV_PROBE_VALUE_NEVER (2)
-			  Never reset device on driver probe.
-			* DEVLINK_PARAM_RESET_DEV_ON_DRV_PROBE_VALUE_DISK (3)
-			  Reset only if device firmware can be found in the
-			  filesystem.
