Hi Dan/Vinod

I am looking to implement scatter/gather interface for mem to mem transfers.
But before that, i wanted to know your feedback about it.

In my case, i have memory scattered in pages and performance is not good, if
i submit transfers page by page.

If you are Okay with the idea, i can implement it and submit soon.
