Adding this to libopenflow in POX just allows you to send the message to the
switch. But you haven't said anything to make me think that you've actually
added the functionality you want to the switch itself (and the error message
backs me up -- the switch is saying that it doesn't understand action type 12).
How you do this depends on the switch you're using. If it's a proprietary
hardware switch, you're probably out of luck. If it's the POX switch
(unlikely), it's in datapaths/switch.py. If it's Open vSwitch (common with
Mininet), you'll need to modify OVS and recompile it. And so on.
Also, I'd point out that rather than just adding a new value (12), OpenFlow has
a "vendor" action type which is meant for non-standard additions.
