From: Lad Prabhakar Add device tree match data and configuration for the Renesas RZ/T2H SoC Ethernet switch. The RZ/T2H uses the same A5PSW switch IP as RZ/N1 but with four ports, the DSA tagging protocol `DSA_TAG_PROTO_RZT2H_ETHSW`, and an additional 8-byte management port frame length adjustment. This prepares the driver to handle RZ/T2H and compatible RZ/N2H Ethernet switch instances.
