RZ/V2M Ethernet is very similar to R-Car Gen3 Ethernet-AVB, though some small parts are the same as R-Car Gen2. Other differences to R-Car Gen3 and Gen2 are: * It has separate data (DI), error (Line 1) and management (Line 2) irqs rather than one irq for all three. * Instead of using the High-speed peripheral bus clock for gPTP, it has a separate gPTP reference clock.
