7title: The NIC functionality of NXP NETC
8
9description:
10  The NIC functionality in NETC is known as EtherNET Controller (ENETC). ENETC
11  supports virtualization/isolation based on PCIe Single Root IO Virtualization
12  (SR-IOV), advanced QoS with 8 traffic classes and 4 drop resilience levels,
13  and a full range of TSN standards and NIC offload capabilities
