To remove assumption, do like followings.

- Add 'attached' member to rte_eth_dev structure.
  This member is used for indicating the port is attached, or not.
- Add rte_eth_dev_allocate_new_port().
  This function is used for allocating new port.

Would it be safer to define DEV_INVALID = 0, then DEV_VALID after it?
Or even as below?
Enum {
	DEV_UNKNOWN = 0,
	DEV_VALID,
	DEV_INVALID
};
