Now I am using the Ethernet of S32K344, and I need mac-to-MAC. I need TO ask NXP technical support for the connection of hardware. Could you please give me a mac-to-MAC case of K3?Thank you so much!!
You can take a look at this board:
There’s either 100BASE-TX PHY DP83848C with RJ45 connector or it is possible to connect external board with PHY like https://www.nxp.com/design/development-boards/analog-toolbox/tja1101-automotive-ethernet-adapter-for...

So, you can use it as a reference.
In case of this board:
… there’s connector for external PHY only.
Also see the hardware design guidelines, there are some comments about ethernet interface:
