v6:
* fix double free problem in v5 as Jay noted
v5:
* fix according to Jay's comment.
* fix anothor bypassing the freeing of memory problem
v4:
* fix compilation issue
v3:
* validate "eth_dev_id" by rte_eth_dev_is_valid_port()
as Ganapati's comment.
* validate "token" by macros to reduce code redundancy.
* use new macros to avoid bypassing the freeing of memory problem.
v2:
* add memory check after strdup
