[BUG] Secondary IP address does not get when USB to ETHERNET device is used

Describe the problem

When using USB to Ethernet dongle to install the fluxnode (option#2)in multitoolbox, the secondary IP address does not get created for the ethernet interface. I have tried both TP-LINK Model UE-300 USB 3.0 to Gigabit Ethernet Adapter and Belkin USB 2.0 Ethernet Adapter F4U047 100Mbps and both have the same issue.

Users will see "Failed: Could not get Node Tier From Flux OS" in the ~/.fluxbenchmark/debug.log and option #3 does not provide helpful insight as to what the problem maybe. Improvement in option #3 is to report if secondary IP is missing and how to fix it.

Temporary Work around is to add the secondary interface manually at boot up via the following commands:

sudo ip addr add <public IP / Netmask> dev

run the following cmd to see the details of the interface: ip addr
priminary IP: LAN IP/netmask
secondary IP : Public IP/netmask <-- this one is missing after multitoolbox install of fluxnode (option #2)

Multiple scripts multitoolbox.sh, nodeanalizerandfixer.sh and install_pro.sh try to locate the physical ethernet adapter on the host using BROADCAST,MULTICAST,UP,LOWER_UP to add the public IP to it. It could pose a problem when using certain USB ethernet adapters, they would return a different string. The exact same problem occurs if you want to self-host your node behind a VPN where ip addr would for example just return POINTOPOINT,NOARP,UP,LOWER_UP on a wireguard interface.
Are there any plans for fixing this in the near future? I suggest adding a whiptail checklist asking the user for the interface to be used among the ones on the host.

i will go in diff direction due not all user are networking expert and solution should work for all
can you dm me on discord :)

[floriangrousset]

Agree, that could add a layer of difficulty for less tech-savvy node operators so better keep it simple as default behavior. What's your handle on the Flux discord? I've looked up for XK4MiLX but can't seem to find you.

------------EDIT--------------
I found you under X4MiLX without the K :) Sending a DM.
