Open Stack

Hi Sean,

Thanks a lot for the clarification.
I am wondering how smart nics attached to a compute node (which runs
ovs-dpdk) can be configured using sdn controllers so that the
ovs/tunneling/ipsec functionality on the compute node is offloaded to
smartnic and compute node cpu is free to do other stuffs?

Thanks,
Hrishikesh
