In this case, the 10GB PCI NIC is presented on slot 6, and the logical bus address of its ports is 5:0 and 5:1.
(See the image in substep c, in which the correlation between PCIe slot and the logical bus address is
highlighted in yellow.)

Bus Address: 0000:05:00.0
b. Correlate the onboard device name (NIC1 to NIC4) to a logical bus address:
dmidecode -t baseboard | sed -n -e '/NIC/,/Bus Address/p' | egrep "NIC|Bus Address"
This command displays the onboard location of each NIC port, In the following sample output, the logical bus
address in the first two lines is "0000:01:00.0" which correlates to physical NIC Integrated NIC 1.
Reference Designation: Integrated NIC 1
Bus Address: 0000:01:00.0
Reference Designation: Integrated NIC 2
Bus Address: 0000:01:00.1
Reference Designation: Integrated NIC 3
Bus Address: 0000:09:00.0
Reference Designation: Integrated NIC 4
Bus Address: 0000:09:00.1
c. Correlate the list of OS interface names to a logical bus address:
ip a | grep ": " | awk '{print $2}' | tr -d ":" | grep -v ^"lo"$ | xargs -I '{}' sh -
c 'echo {}; ethtool -i {} | grep bus-info'
This command displays the Ethernet network names (enXXX) of the interfaces and the correlating logical bus
address (without the loopback). For example:
em1
bus-info: 0000:19:00.0
p1p1
bus-info: 0000:3b:00.0
em2
bus-info: 0000:19:00.1
em3
bus-info: 0000:19:00.2
em4
bus-info: 0000:19:00.3
p1p2
bus-info: 0000:3b:00.1
