Hi Ben,
With this fix, flow add/mod/del are not allowed on table=254. Is this 
the intended behaviour?
We may want to just avoid deleting following internal flows instead of 
reserving the table itself.

Please correct if my understanding is wrong.

# ovs-ofctl dump-flows br0 table=254
  cookie=0x0, duration=606.191s, table=254, n_packets=0, n_bytes=0, 
idle_age=606, priority=1 actions=drop
  cookie=0x0, duration=606.191s, table=254, n_packets=0, n_bytes=0, 
idle_age=606, priority=0,reg0=0x3 actions=drop
  cookie=0x0, duration=606.191s, table=254, n_packets=0, n_bytes=0, 
idle_age=606, priority=0,reg0=0x1 actions=controller(reason=no_match)
  cookie=0x0, duration=606.191s, table=254, n_packets=0, n_bytes=0, 
idle_age=606, priority=0,reg0=0x2 actions=drop
  cookie=0x0, duration=606.191s, table=254, n_packets=0, n_bytes=0, 
idle_age=606, priority=2,recirc_id=0 actions=resubmit(,0)
