> It was observed that Tx performance was inconsistent across all queues and/or VSIs and that it was directly connected to existing 9-layer topology of the Tx scheduler.
>
> Introduce new private devlink param - tx_scheduling_layers. This parameter gives user flexibility to choose the 5-layer transmit scheduler topology which helps to smooth out the transmit performance.
>
> Allowed parameter values are 5 and 9.
>
> Example usage:
>
> Show:
> devlink dev param show pci/0000:4b:00.0 name tx_scheduling_layers
> pci/0000:4b:00.0:
>   name tx_scheduling_layers type driver-specific
>     values:
>      cmode permanent value 9
>
> Set:
> devlink dev param set pci/0000:4b:00.0 name tx_scheduling_layers value 5 cmode permanent
>
> devlink dev param set pci/0000:4b:00.0 name tx_scheduling_layers value 9 cmode permanent
