onlpdump -b returning default output and not SFF database entries

[ramarn7]

It looks there is no API called for -b option in onlpdump implementation.
https://github.com/opennetworklinux/ONLP/blob/master/modules/onlp/module/src/onlp_main.c

I am getting default onlpdump output when executing onlpdump -b.
But as per onlpdump help options, it should display "Decode SFP Inventory into SFF database entries."

Please provide your input is this option really supported and how to make it work ?
