hi,
imho you're on your way at least your configs look good except that
you have 2 physical interfaces binded to vfio so i bet you the p4dpdk
uses the cpuport index 2 (the 3rd interface) so please do the following in 
-hw..txt instead:
proc p4emu /bin/p4dpdk.bin --vdev=net_af_packet1,iface=veth0b -- 127.0.0.1 
9080 2
note the final 2... also you can split the load between the cores but let the 
fine tuning after your first packets...
assuming nothing more logs on freerouter imho the dataplane is connected...
sho p4 p4 stat
sho p4 p4 port-na
if not, then "reload process p4emu stop" followed by "sudo /bin/p4dpdk.bin 
--vdev=net_af_packet1,iface=veth0b -- 127.0.0.1 9080 2"
br,
cs
