I think this one flag is conflating too many things then.
Obviously sending out of order packets is not spec conformant, and I
don't think your discussion is clear enough, as this change to send
side certainly was not clear to me.
I'm not excited about a new end-to-end flag without some kind of
negotiation scheme, and I'm not excited about this being in any of the
common APIs.
Perhaps it should be in libmlx5 instead.
