If your install a flow entry without any actions it should cause the
datapath to drop the packet.
If you check out core.py that would probably help to clarify but in
general you do something like this if you want to perform rewrite:
actions = [
[openflow.OFPAT_SET_DL_SRC, mac_to_int(inst.Agent[HA]['mac']) ],
[openflow.OFPAT_SET_DL_DST, mac_to_int(inst.Agent[FA]['mac']) ],
[openflow.OFPAT_SET_NW_SRC, inst.Agent[HA]['ip']],
[openflow.OFPAT_OUTPUT, [0, inst.Agent[FA]['inport']]]
]
