PM in PMD stands for "Poll Mode". DPDK provides poll mode drivers
for network devices. It means that there are no interrupts or any
other wake up mechanism to notify that there are some packets

This is perf result, it shows mlx5_rx_burst_vec function is called

Hi all,
I'm using ovs-dpdk version 2.13 in openstack(openstack is deploy by
kolla-ansible(https://docs.openstack.org/kolla-ansible/latest/)).
After I reboot hipervisor, I found high cpu usage of pmd thread in
ovs-dpdk. But there is no large log or large packets, how to know what's
the problem?
