Summary: Thanks for the work. This document is clear in the problem to be
solved . This document is ready to be published as it-is, however I do have few
clarification questions for my own understanding

Major issues:

Minor issues:

Nits/editorial comments:
1. The draft doesn't specify normative procedures on sender/receiver behavior
when certain fields are missing (say size of all zeroes). Should the draft say
recommended procedures for handling these scenarios ?

2. Also i didn't see fallback procedures to be followed when the server
reported size isn't of much use to the sender of the data . In such case the
sender might decide to go with existing explicit RDMA data transfer operations
instead of failing the connection ?
