[ovs-dev] [PATCH] Update tutorial for newer versions of Faucet and Open vSwitch.
Newer versions of Faucet use a dynamic OpenFlow pipeline based on what features are enabled in the configuration file. Update log output, flow table dumps and explanations to be consistent with newer Faucet versions. Remove mentions of bugs that we have since fixed in Faucet since the tutorial was originally written. Adds documentation on changes to Open vSwitch commands to recommend using a version that is compatible with the features of the tutorial.
