Thanks for the reply Numan! When I use the OVS submodule for OVN compilation, I don't have any issues. Also when I compile OVS with DPDK libraries configured as "shared", I don't see any issues.
A question here: If I don't use DPDK with OVS for compiling and installing OVN, can I still use OVS with DPDK installed with this new OVN?
