Hi ,
We have brought up topology as below with OpenVSwitch 2.3.9 /DPDK enabled .
Sending 128 bytes of frame as bidirectional from Agilent N2X(traffic
generator) and observed that , in OVS we have found many errors(marked in red
colour) in dump-ports.

Just checking - you are using OVS with DPDK and not OVDK as per the diagram?
I see it is with dpdk as mentioned in the beginning of mail.
<cut>
tx pkts=1180319172, bytes=?, drop=11522, errs=?, coll=?
I'm not quite sure I understand your setup, but the first thing I would check
is that you are affinitising your cores so that you are not trying to run a
pmd and other VM processing on the same core. You can use top -H and taskset.
I too noticed many other fields with value "?" for vhost-user port,
where as it is normally
showing packets/bytes count for other port types. I checked with both
ofctl dump-ports
and appctl dpctl/show -s .
port 1: rx pkts=2581437, bytes=183201033, drop=0, errs=0, frame=0,
over=0, crc=0
tx pkts=45101499, bytes=67075737796, drop=0, errs=0, coll=0
port 2: rx pkts=45101499, bytes=?, drop=?, errs=?, frame=?, over=?,
crc=?
tx pkts=2581370, bytes=?, drop=0, errs=?, coll=?
As per netdev_dpdk_vhost_get_stats(), only rx/tx_packets and tx_drop
counts are supported
and I was curious to know logic behind it, though I am checking code to
assist myself.
Could anyone clarify on why only packets count are supported for dpdk ?
