[ovs-discuss] could not find the flows in openflow swtich

[Ben Pfaff]

Waqas, it looks like you are using the OpenFlow reference implementation, not
Open vSwitch, because the message "cannot look up controller hw address"
appears in the OpenFlow reference implementation source code but not in
Open vSwitch source code.

For help with OpenFlow, please try one of the OpenFlow mailing lists.  For help
with NOX, please try one of the NOX mailing lists.
