Hi Greg k-h,

My sincere apologies for responding privetly on the original
submission, It was not intended to do so. There was some issue
while responding via mutt and I end up responding privetly.

I have responded publicly on original submission as well. Please 
consider this second version, I have taken care of some previous
reviews.

Thanks Rafael, for the review comments as well, I will be respondig
to the queries in a seperate thread.  


Warm Regards,
Vimal Kumar
