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. > >Laurent > > Regards, Keith
