[ovs-dev] Query regarding (Open vSwitch) 2.0.0 version

[hardik soni]

What needs to be done o change the route of packet by modifying destination
IP and MAC?
I have been able to match the flow based on src and dest MAC only. I want
to match is based on src IP and dest UDP port.
I am not able to do that because of flows added in response of pings.

Thanks.
