Match field

John Schistos <jschistos@...>

I'm passing flows from my app to switches with sal-flow:add-flow.I want , in the flow that I am passing, to be able to alter the ipv4-src match field, and use a match field of my own.What I mean exactly:I want for example to use a ipv4 prefix match in the flow.That's an example not what I want but I think you get the point.How exactly am I able to do that?Is it by the use of augmentation in yang?And if yes, can you give me an example on my example above?I would really appreciate your help.
Thanx in advance.
