I am implementing a simple switch for OpenFlow 1.3 and I need to
retrieve the in_port value from the match fields. To do that I need to
search the list for the field (as the specification doesn't require
ordered fields).
My suggestion is to have a dictionary instead of a list to ease the
access to the fields, using the header as the key. Something like:
in_port = msg.match.fields[ofproto.OXM_OF_IN_PORT].value
I implemented a patch for this. If you think it's good, or have
suggestions, I can submit to the developer list.
