One more suggestion is to run test_pmd on one machine and something like iperf on the other to verify the DPDK is working correct, which I assume will be true. Not sure the RX errors are reported in the test_pmd or you could use the l3fwd application too.
Please also send me the 'lspci | grep Ethernet’ output.
Also send me the command line.
