AM243x - ICSS EMAC vs ENET

Hello,
I am working on an Sitara AM243x Board and need to access device informations on the
onboard ethernet adapters.
So I need to load a driver from the MCU+ SDK.
And here I am not sure which one to pick.
First I thought it would be ENET:

but now I am not sure what the difference is to ICSS EMAC:

https://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_03_00_106/rtos/index_pru_icss_fw.html




Do I need both for different layers or what is the difference?
Thank you for your help.


Best regards

Philip.
