NVMe I/O Submission

I/O is submitted to an NVMe namespace using nvme_ns_cmd_xxx functions defined in nvme_ns_cmd.c. The NVMe driver submits the I/O request as an NVMe submission queue entry on the queue pair specified in the command. The application must poll for I/O completion on each queue pair with outstanding I/O to receive completion callbacks.
