22       -c <cntid>, --controller-id=<cntid>
23           Retrieve the identify I/O Command set data structure for the given
24           cntid. If this value is not given, cntid will be 0xffff.
25
26       -H, --human-readable
27           This option will parse and format many of the bit fields into

36           known fields in a human readable format:
37
38               # nvme id-iocs /dev/nvme0
39
40       •   show the fields in human readable format
