Merge pull request #44 from InCNTRE/Grp30No80_1

Earlier all ports are set to be in flood mode which is the default, changed code to set only half ports to flood and check the behavior. Earlier flood rule was added with match on dst ip (244.0.0.1) but a normal tcp packet was being sent on data plane to check flood behavior and since flood bits were set by default, the test case passed. Now changed the packet sent on datapath to have dst ip 244.0.0.1.
