Hello,
I am new to DPDK and writing the code in c++ language, currently working on
IP reassembling the packets below is my sample code which is giving me
segmentation fault for rte_ip_frag_table_create, I am unable to debug the
issue. Much appreciated if someone can explain to me where did I go wrong
and how to do it in a proper manner. At the moment I am finding it
difficult. Thanks in advance.
