A number of APIs support a buf_align parameter but we haven't been terribly precise about limits on this, so some questions for Petri.
With buf_align being defined as uint32_t in theory we can specify alignments up to 2GB. 1. MAY implementations impose a lower upper limit on the alignments they support? 2. If so, what is the minimum acceptable upper alignment limit? We've specified that buffers MUST be at minimum 8 byte aligned but is that sufficient? 3. If implementations MAY impose an upper alignment limit below 2GB, what SHOULD happen if an application requests an alignment above this limit? Fail the request? Saturate at the implementation-defined max alignment? Thanks.
