This adds support for the Marvell switch and names the network ports according to the labels, that can be found next to the connectors. The switch is connected to the host system using a PCI based network card. The PCI bus configuration has been written using the following information: root@b650v3# lspci -tv -[0000:00]---00.0-[01]----00.0 Intel Corporation I210 Gigabit Network Connection root@b650v3# lspci -nn 00:00.0 PCI bridge [0604]: Synopsys, Inc.
