Error on running device-statistics.lua example
We are trying to run the device-statistics.lua example. The destination and source NICs(Intel(R) Ethernet Converged Network Adapter XXV710-DA2 (2x25G)) are on the same machine. Because we know the mac address of the destination NIC, we are hardcoding it. We are able to transmit the packets from one of the NICs but it is not being received by the destination NIC.
Few questions we have are:
- Can this example be run with 2 NICs on the same machine?
- Both of our NICs are dpdk bound. Is that an issue?
Appreciate your help!
can you post the exact model number of this NIC?

Output of lspci command:

Same symptom here with: 3b:00.0 Ethernet controller: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ (rev 02) 3b:00.1 Ethernet controller: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ (rev 02)
On the switch I'm seeing nearly all the packets as RX_DROP.

Now, of possible interest, I am seeing traffic on this card and intel firmware work fine for some of the tests and no RX(dropped by switch, which points to checksum failure or the like) on other tests:
