Hello,
I am trying to allocate an mbuf to use for IP fragmentation. When instantiating a mempool using rte_pktmbuf_pool_create() function, I keep getting the following error message.
Error Message:
* MEMPOOL: Cannot allocate tailq entry!
Will you please let me know what I am missing?
Regards,
Katie
