Johannes Thumshirn 637dc0f38a nvmet: implement namespace identify descriptor list ... A NVMe Identify NS command with a CNS value of '3' is expecting a list of Namespace Identification Descriptor structures to be returned to the host for the namespace requested in the namespace identify command. This Namespace Identification Descriptor structure consists of the type of the namespace identifier, the length of the identifier and the actual identifier. Valid types are NGUID and UUID which we have saved in our nvme_ns structure if they have been configured via configfs. If no value has been assigened to one of these we return an "invalid opcode" back to the host to maintain backward compatibiliy with older implementations without Namespace Identify Descriptor list support. Also as the Namespace Identify Descriptor list is the only mandatory feature change between 1.2.1 and 1.3 we can bump the advertised version as well.
