In OpenFlow 1.0, mod_nw_src is allowed even on non-IP packets.  In
OpenFlow 1.1 and later, mod_nw_src is only allowed on IP packets, so
to make this work with OF1.3, add "ip" to the match:

ovs-ofctl -O OpenFlow13 add-flow br0 in_port=9,ip,actions=output:1,mod_nw_src:'192.1.1.1',controller:663

(However, "controller:663" doesn't make much sense.  Please make sure
that you understand what it means.)
