Hi Mohammed I am trying to create the patch similar to yours: https://gerrit.fd.io/r/c/vpp/+/31876 But being able to run on Ubuntu. Can you point me a bit? I would like to understand how your patch is CentOS specific. Probably it has something to do with linking of libibverbs.so into dpdk_plugin, which I was not able to achieve yet. Or am I completely wrong?
