It seems likely that the encode_*() function that you wrote does not
properly encode the new action.  Does it use the generated
ofpact_put_*() function to encode the action?  I would also check the
hexdump for the action to make sure that it has the expected format.

You do need a "vendor extension" or "experimenter" action but the
generated ofpact_put_*() function should take care of that for you.
