 Description   

steps to reproduce:

1) connect odl with mininet (without any flows)
checking /restconf/operational/opendaylight-inventory:nodes/node/openflow:1/table/31/opendaylight-flow-table-statistics:flow-table-statistics
for tables 30 and 31 should return

{
"opendaylight-flow-table-statistics:flow-table-statistics":

{ "packets-looked-up": 0, "active-flows": 0, "packets-matched": 0 }

}

2)generate 100k flows( use attached script) 50k for each table
bash flowscreator.sh -f 50000 -t 30 -o t30f50k
bash flowscreator.sh -f 50000 -t 31 -o t31f50k

3) add the first 50k of flows to switch
sudo ovs-ofctl add-flows s1 t30f50k -O OpenFlow13

after some time you should see flows reported in table 30
{
"opendaylight-flow-table-statistics:flow-table-statistics":

{ "packets-looked-up": 0, "active-flows": 50000, "packets-matched": 0 }

}

4) add another 50k of flows to switch
sudo ovs-ofctl add-flows s1 t31f50k -O OpenFlow13

what happened to me was that i never saw any "active-flows" in table 31 (table 30 was reported ok)
or
urls like .../table/XX/opendaylight-flow-table-statistics:flow-table-statistics; ..table/XX start returning 404 where XX is anything, not only 30 or 31
