Resubmit actions are changed to drop after rebooting the control node.

Also, other attributes of the flow (e.g. ct_mark) are also missing.</p> <ul> <li>this is the case regardless of the OVS fail_mode setting of the bridge, which determines whether the original flow is cleared by OVS between step 1. and 2. (i.e. after ODL disconnects).</li> </ul> <p>workaround: if you restart openvswitch on the node after step 3., the correct flow is pushed down to the node.</p> <p>e.g.<br/> <span class="error">&#91;odl@odl32 ~&#93;</span>$ sudo ovs-ofctl dump-flows -Oopenflow13 br-int<br/> OFPST_FLOW reply (OF1.3) (xid=0x2):<br/> cookie=0x6900000, duration=21.207s, table=2, n_packets=0, n_bytes=0, priority=62020 actions=drop<br/> <span class="error">&#91;odl@odl32 ~&#93;</span>$ sudo systemctl restart openvswitch<br/> <span class="error">&#91;odl@odl32 ~&#93;</span>$ sudo ovs-ofctl dump-flows -Oopenflow13 br-int<br/> OFPST_FLOW reply (OF1.3) (xid=0x2):<br/> cookie=0x6900000, duration=2.392s, table=2, n_packets=0, n_bytes=0, priority=62020,ct_mark=0x24/0x37 actions=resubmit(,17)</p> <p>stable/carbon:<br/> reproducible most of the time.
