But certain drivers can offload only certain combinations of settings, like for example they cannot change unicast flooding independently of multicast flooding - they must be both on or both off. The way the information is passed to switchdev makes drivers not expressive enough, and unable to reject this request ahead of time, in the PRE_BRIDGE_FLAGS notifier, so they are forced to reject it during the deferred BRIDGE_FLAGS attribute, where the rejection is currently ignored. This patch also changes drivers to make use of the "mask" field for edge detection when possible.

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).

In particular report to user-space rx packets even if they are not forwarded to the networking stack (XDP_PASS) but if they are redirected (XDP_REDIRECT), dropped (XDP_DROP) or sent back using the same interface (XDP_TX).
