Many ovs netdevs support collecting this counter, such as netdev-linux, netdev-dpdk, netdev-bsd and so on. But as far as I know, this counter can't be read by command "ovs-vsctl list interface <int-name>|grep statistics". I have found the root cause(may be I was wrong) is in task "iface_refresh_stats", the "rx_missed_errors" is not in the macro IFACE_STATS. So even if this counter is updated by netdev, it woundn't be read by users.
