What is a support > chunk? What does "multi chunk high" mean? Please add a comment. HPB1.0 limits transfer_len to be at most 1. HPB2.0, which is in its final draft, allows transfer_len to be at most 128, But introduce some new behavior depends on transfer_len. This is just preparing for that.
Thanks, Avri
