Comment 10 for bug 1858610

Hi Rodolfo:
[ovs-dpdk]
network packets will not go through hypervisor host's kernel, so linux tc will not work under this
architecture. ovs-dpdk has qos function, but it depends on dpdk liberity. so if we want to implement shared-qos-policy with dpdk lib, it will be complicated.

[sriov]
users use sriov with openstack want to speed up the network performance, so i think it may be inappropriate to redirect network packets to ifb interface. As you mentioned above, it will reduce I/O.

we probably implement the first version without considering the ovs-dpdk and sriov.
