Hi Helin
I would like to add my input for this as well.
I encountered the same issue, and as you suggested I updated to the latest
fw and changed rx and tx ring sizes to 1024.
Drop counters still do not increment as they should.
I Inject 10mpps into an x710 nic (a 4 ports card, 10mpps on each po
Hi Martin
Could you help to try bigger size of rx/tx ring, but not the default sizes?
For example, could you help to try 1024 for RX ring size, and 512 or 1024 for
TX ring size.
In addition, please make sure you are using the latest version of NIC firmware.

Hi Helin,
good to know that there is work being done on that issue.
By performance problem I mean that theses packet discards start to
appear at low bandwidths where I would not expect any packets to be
dropped. On the same system we can reach higher bandwidths using ixgbe
NICs without loosing a s
Hi Martin
Yes, we have a developer working on it now, and hopefully he will have
something soon later on this fix.
But what do you mean the performance problem? Did you mean the performance
number is not good as expected, or else?

Hi Helin,
any news on this issue? By the way this is not just a problem with
statistics for us but also a performance problem since these packet
discards start appearing at a relatively low bandwidth (~5GBit/s and
~1.5Mpps).
Best regards,
Martin

Hi Helin,
in one of our test setups involving i40e adapters we are experiencing
packet drops which are not reflected in the interfaces statistics.
The call to rte_eth_stats_get suggests that all packets were properly
received but the total number of packets received through
rte_eth_rx_burst is les
