1. If you change any of the code generation scripts in tools/munger/scripts you must re-run 'make -C tools/munger' to regenerate the OpenFlow message classes.

2. If your running into issues with transactions, and it appears that OpenFlow messages aren't quite right, start by looking at any length fields in the packets. With the local platform, you can use wireshark on the loopback interface as well as the dataplane veth interfaces.

3. If tests dealing with VLANs fail unexpectedly then try installing pypcap (see Longer Start above).
