Report more information about network interfaces

[MateuszGrabuszynski]

It would be helpful to provide additional information about the network interfaces and cards, including virtual functions associated with those interfaces.

Extend NIC with numbered Physical Cards and Ports

Name	...	Card / Port
eth2	...	1 / 1
eth3	...	1 / 2
eth0	...	2 / 1
eth1	...	2 / 2

Provide additional section for Virtual Functions

Bus	Name	Associated interface
0000:c0:11.0	Ethernet Adaptive Virtual Function	eth0
0000:c0:11.1	Ethernet Adaptive Virtual Function	eth0
0000:c0:11.2	Ethernet Adaptive Virtual Function	eth0

I see two ways it could be done:

1. By checking the memory mapping under lshw -c network
   • physical interfaces on a card share the same iomemory regions (always?), and the bus address start
   • virtual interfaces use memory regions from physical card's memory space
2. Using files under /sys/bus/pci/devices in a manner similar to this script https://github.com/OpenVisualCloud/Media-Transport-Library/blob/main/script/nicctl.sh (BSD-3-Clause)
