Hi，

Questions about TI mac to mac solution documentation：

1.The screenshot above shows that CPSW2G is A72 control.  CPSW9G is the main R5F control. 

2. But the screenshot above. Say it differently.
CPSW2G is MCU Domain 。CPSW9G is main Domain。

？？？

3.  How to on the A72 linux side. set mac tomac mode？

The patch given before does not correspond to the document

    Yes, CPSW2G is from MCU Domain and default A72 has native Ethernet Driver for it.
    CPSW9G is from Main Domain and default Main R5F0_0 (MCU2_0) has Ethernet switch firmware and server application, MCU2_1 and A72 has Ethernet virtual configuration and client application.

    For CPSW2G, we need to set in Device tree if we are using A72 based native Ethernet Driver.
    For CPSW9G, we need to set in Ethernet Firmware MAC Port configuration. 

    If you are using PDK application then you have to change enet module of PDK example application.
