The Intel ports are 0 and 1, while the Mellanox ones are 2 and 3. I properly compiled DPDK 16.11 and test-pmd works just fine for all 4 ports. Then, I ran a simple primary application that forwards packets from 0 <--> 1 and 2 <--> 3 and started dpdk-procinfo -- --stats (or --xstats) as a secondary monitoring process, while sending some traffic to all 4 ports. The problem I see is that the statistics reported by the Mellanox NICs are always zero (Intel ports report just fine). What is the reason behind this behavior? Is there a bug in the driver (maybe recently fixed by DPDK 17.02 rc?) or is it simply a lack of this functionality?
