In the Jetson_AGX_Orin_Series_Design_Guide
, following description was mentioned.
The MGBE Controller #0 mentioned in the above description is mapped to the MGBE(C0) in the following UPHY2 mapping table?
The MGBE-A (ethernet@6810000) device node mentioned in the tegra234-ethernet-3737-0000.dtsi device tree file also refers to MGBE Controller #0
?
