Information that would be useful for the ioctls:
1. Which fd the ioctl must be invoked on (/dev/nitro-enclaves, enclave fd, vCPU fd)
2. Errnos and their meanings
3. Which state(s) the ioctls may be invoked in (e.g. enclave created/started/etc)

Where is the write flag defined?
I guess it's supposed to be:
#define NE_USER_MEMORY_REGION_FLAG_WRITE (0x01)
