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@b850v3# lspci -tv -[0000:00]---00.0-[01]----00.0-[02-05]--+-01.0-[03]----00.0 Intel Corporation I210 Gigabit Network Connection +-02.0-[04]----00.0 Intel Corporation I210 Gigabit Network Connection \-03.0-[05]-- root@b850v3# lspci -nn 00:00.0 PCI bridge [0604]: Synopsys, Inc.
