+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. If enabled, adapter will ignore 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
+ physical functions (PFs) in the device.
+ 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
