Flow-mod is the most variable command of dpctl. The number of match fields, instructions and actions, always raise doubts on how to add some specific flow. So this page aims to be a reference for people starting to get used with the wide range of possibilities that flow mod brings.
We will start start with lists of all match fields, instructions and actions, because the first doubt is always: How is that field named?
