- This driver supports network switches from the Vitesse /

- connected to their host CPU via Ethernet.
- The following switches are supported:
- - VSC9959 (Felix): embedded as a PCIe function of the NXP LS1028A
- ENETC integrated endpoint.
- - VSC9953 (Seville): embedded as a platform device on the
- NXP T1040 SoC.
