We did this slightly differently. This is 100% python and is a bit more general.

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:
quoted hunk ↗ jump to hunk
+ 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. John
