ovs-ofctl dump-ports shows question marks ('?') in OVS DPDK environments in Red Hat OpenStack Platform
Issue
ovs-ofctl dump-ports shows question marks (?) in OVS DPDK environments in Red Hat OpenStack Platform.
What is the reason for ? across some of the statistics in the output of ovs-ofctl dump-ports.
For example:
[root@overcloud-compute-0 openvswitch]# ovs-ofctl dump-ports br-int
OFPST_PORT reply (xid=0x2): 6 ports
