Will you please help me in understanding, how should I do it?

1. The is no standard librte_mbuf initialization routine. RTE_INIT will 
not work, as it will be executed before eal_init. dlopen is for shared 
lib only. Is there any other method?

2. If I call it on the very first call of rte_mbuf_user_mempool_ops_name 
or rte_mbuf_set_user_mempool_ops_name, I will be checking against NULL. 
It can be NULL always. So, no real meaning of maintaining it in 
librte_mbuf as well.
Yes, I can maintain a flag to know, If I have synced with eal parse 
before. But that is not sounding to me clean.
