Subject: [dpdk-users] DPDK: IP reassemble segmentation fault for rte_ip_frag_table_create.
Date: Mon, 19 Oct 2020 12:35:10 +0200 [thread overview]
Message-ID: <CAPk29mLVRj4Yj_AtPnAbBzTxzPgtz8JXnHh8+j0SS7003DBa-w@mail.gmail.com> (raw)
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.
