Hello,

My code consists of these statements,

learn.spec.append(fms( field=nx.NXM_OF_ETH_DST, match=nx.NXM_OF_ETH_DST ))
learn.spec.append(fms( field=nx.NXM_OF_ETH_TYPE, match=nx.NXM_OF_ETH_TYPE ))
learn.spec.append(fms( field=nx.NXM_OF_IP_PROTO, match=nx.NXM_OF_IP_PROTO ))


If the last time is added then it throws an error like below,


INFO:core:POX 0.2.0 (carp) is up.
