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.

PFA logs attached for your ref . Please let me know , is it OVS capable of
supporting 1 gig throughput and let me know to resolve these errors.
Thanks
