The ENETC of i.MX95 has been upgraded to revision 4.1, and the vendor ID and device ID have also changed, so add the new compatible strings for i.MX95 ENETC. In addition, i.MX95 supports configuration of RGMII or RMII reference clock.

title: The NIC functionality of NXP NETC
|
|
|
|
description:
|
|
The NIC functionality in NETC is known as EtherNET Controller (ENETC). ENETC
|
|
supports virtualization/isolation based on PCIe Single Root IO Virtualization
|
|
(SR-IOV), advanced QoS with 8 traffic classes and 4 drop resilience levels,
|
|
and a full range of TSN standards and NIC offload capabilities
