as i understand it, if the packets end up being processed at the
controller (nox_core running pyswitch.py in this case), "return STOP"
will cause them to drop, and "return CONTINUE" will cause them to
continue to be processed and thus forwarded.  installing the flow
entry at the switch (datapath) causes them not to even reach the
controller in future unless so directed by the flow entry's action.

(i also had similar problems when setting all this up on a single
machine managing a single ethernet interface, but they went away once
i moved to openvswitch, albeit to be replaced by other ones which i'm
still in the process of understanding :)
