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?

Regards,
Spoorthi
