 * All sgfru ioctls accept either a fru_info_t (a handle and a count),
 * a frup_info_t (which is a fru_info_t plus a pointer to a preallocated
 * data buffer), or an append_info_t (which is a packet_t plus a frup_info_t).
 *
 * The count is always the space allocated for a specific number of items,
 * aka the calloc model.
