Thanks for the patches. I agree to convert to bits and pass it as int value which is extensible i.e. we can pass more extra parameters across if required. Also I'm not in favour of removing relids_extra altogether, we might need this to send some info in future. Both 0001 and 0002(along with the new phrasings) look good to me.
