Thanks for the response Jarno. I do not see the error message I was
facing earlier with your steps.

But goto_table:1 instruction gets treated like a NOOP.
# ovs-vsctl set bridge br0 protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13
# ovs-ofctl -O OpenFlow13 add-flow br0
"table=0,dl_dst=aa:bb:cc:dd:ee:ff,actions=goto_table:1"
# ovs-ofctl dump-flows br0
NXST_FLOW reply (xid=0x4):
 cookie=0x0, duration=3.922s, table=0, n_packets=0, n_bytes=0,
idle_age=3, dl_dst=aa:bb:cc:dd:ee:ff actions=drop
#

In other words, rather than goto_table:1 in the dump_flow output, I
see only Drop.
Feel free to correct in case I'm missing something.
