AM65 NUSS ethernet switch on K3 devices can be configured to work either in independent mac mode where each port acts as independent network interface (multi mac) or switch mode. Add devlink hooks to provide a way to switch b/w these modes. Rationale to use devlink instead of defaulting to bridge mode is that SoC use cases require to support multiple independent MAC ports with no switching so that users can use software bridges with multi-mac configuration (e.g: to support LAG, HSR/PRP, etc). Also, switching between multi mac and switch mode requires significant Port and ALE reconfiguration, therefore is easier to be made as part of mode change devlink hooks. It also allows to keep user interface similar to what was implemented for the previous generation of TI CPSW IP (on AM33/AM43/AM57 SoCs).
