Okay so how about that to use the function argument unsigned int flags 
instead with adding the NVME_IOCTL_FABRICS enum definition?
enum {
     NVME_IOCTL_VEC        = (1 << 0),
     NVME_IOCTL_PARTITION    = (1 << 1),
};
Note: I mean as possible as we can it seems better to avoid the many 
function arguments for the maintainability.
Thank you.
