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
