Hi Gary,
That looks like a cleaner solution. Could you submit that as a patch.
Souvik, could you test this patch and confirm it fixes your issue.
Gary, if you submit a patch could you make a few minor changes:
> + device["Interface"] = ""
> + for base, dirs, files in os.walk("/sys/bus/pci/devices/%s/" % dev_id):
> +
If "files" is unused, and it looks like it is, then replace it with "_".
> + device["Interface"] = ",".join(os.listdir(os.path.join(base,"net")))
There is a space required after "," for PEP8 compliance.
