[SPDK] Re: NVMe 2.0 support

Hi, Jim

Yes, at present we are looking at the enhanced end-to-end data protection, for example, 16-byte PI. 

Some new features in NVMe2.0 also involve fundamental data structure changes, e.g. additional fields in Identify structure. Controller registers also have new members, like CRTO register. Not sure how SPDK would support individual features without compliance to a specific NVMe version? 

Thanks
