[nox-dev] Wildcard rules and priority weird behavior

[Dushyant Arora]

Hello,

I have been trying to install 2 wildcard rules from my controller
application and using ovs-ofctl to check if the flow rules have been
installed properly. Here is the code:

def datapath_join_callback(dpid, stats):
    if dpid == 0x112233445566:
      flow = {}
      flow[core.NW_DST] = ipstr_to_int('10.16.0.2')
      actions = [[openflow.OFPAT_OUTPUT, [0, 2]]]
      inst.install_datapath_flow(dpid, flow,  openflow.OFP_FLOW_PERMANENT ,
openflow.OFP_FLOW_PERMANENT, actions, None, openflow.OFP_DEFAULT_PRIORITY,
None, None)

      flow = {}
      flow[core.NW_DST] = ipstr_to_int('10.16.0.1')
      actions = [[openflow.OFPAT_OUTPUT, [0, 1]]]
      inst.install_datapath_flow(dpid, flow, openflow.OFP_FLOW_PERMANENT,
openflow.OFP_FLOW_PERMANENT, actions, None,
openflow.OFP_DEFAULT_PRIORITY , None, None)

For some reason only the second flow rule shows up when I dump flows of the
switch using ovs-ofctl. But if I change the priority of one of the rules,
both of them show up. What is going on here?

Thanks,

Dushyant
