> Introduce support for Tx scheduler topology change, based on user selection, from default 9-layer to 5-layer.
> Change requires NVM (version 3.20 or newer) and DDP package (OS Package
> 1.3.30 or newer - available for over a year in linux-firmware, since commit aed71f296637 in linux-firmware ("ice: Update package to 1.3.30.0"))

>
> Enable 5-layer topology switch in init path of the driver. To accomplish that upload of the DDP package needs to be delayed, until change in Tx topology is finished. To trigger the Tx change user selection should be changed in NVM using devlink. Then the platform should be rebooted.
