hi,
let's dissect it a bit because your rtr-hw.txt seems to have some issues...
- you did not spawn the cpu port (eth0) handler.... it needs a veth in linux 
and that need to be passed to both freerouter and the dpdk...
- you missed the 'proc' knob before /rtr/p4dpdk.bin, you just entered the 
executable name which is not a valid -hw command in freerouter...
- your p4dpdk parameters seems a bit mess... it's 127.0.0.1 9080 0 and the 
rest.... and that 0 also seems bad because this way you
  delegate your first physical nic as cpuport, which is not the case imho... 
it should be the dpdk index of the veth described above...
  this, assuming the only veth you give to dpdk is the cpuport is the number 
of physical interfaces...

for your quick reference, i ran the below command on the 
http://dl.nop.hu/rtr.vmdk image:
yourname#test hwext path /rtr/rtr- dataplane p4dpdk
i arrived to the following working configuration:
