Recently i have added come compute nodes in cloud supporting
openvswitch-dpdk for performance. I am seeing all my PMD cpu cores are
100% cpu usage on linux top command. It is normal behavior from first
looks. It's very scary to see 400% cpu usage on top. Can someone
confirm before I assume it's normal and what we can do to reduce it if
it's too high?
