First, this conversation seems to be more about OpenFlow than nox... I would suggest if you want more responses, you might consider moving it to the openflow-discuss mailing list.
Second, the uin32_t actions in switch_features is an array of flags to describe which actions are *supported* by the switch. You specify actions in a flow_mod or packet_out packet, which both have variable length action payloads. For example, if you look at struct ofp_flow_mod, the length of the message, minus the length of the structure is the number of bytes of actions specified. To parse them, read the action header of the first action, look up the length, and the next action starts that many bytes later. Let me know if this is not clear, but there are notes in the header file that also try to explain this. - Rob .
