Thanks,  when I changed the ovs version to 3.6.0, flows gets offloaded.   I 
could see that  “ovs-appctl dpctl/dump-flows -m type=offloaded”.  But now  
stats sync are not getting called. I added
Prints in netdev_tc_flow_get() and figured out that it is not hitting.  So flow 
gets deleted by netdev_tc_flow_del() after some time. When  I used  "ovs-vsctl 
set Open_vSwitch . other_config:max-idle=30000" command to
to increase the idle time flow delete takes a little more time. 

Thanks,
Ratheesh
