Lukasz Czapnik 109eb29172 ice: Add tx_scheduling_layers devlink param ... 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 Signed-off-by: Lukasz Czapnik <lukasz.czapnik@intel.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Co-developed-by: Mateusz Polchlopek <mateusz.polchlopek@intel.com> Signed-off-by: Mateusz Polchlopek <mateusz.polchlopek@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>		2024-04-22 13:05:19 -07:00
