Hi, dpdk.
I'm trying to develop custom application using DPDK but I have a problem
now.
When I use multi-core for my application, 'rx_errors' counter increases. I
set one rx, tx queue per core and get counter information using
rte_eth_get_xstats(). I'm using DPDK version 20.05 and tried with 21.05 but
the same result happens. I'm using Mellanox BF-2 SmartNIC, and mlx5 NIC
driver. I ran my application both on host CPU and embedded ARM core of
SmartNIC. But, problem happens at host CPU(increasing 'rx_errors" counter).
Here is the full list of counter that I got using rte_eth_get_xstats().
Port 0: _______ rx_good_packets: 587188
Port 0: _______ tx_good_packets: 587696
Port 0: _______ rx_good_bytes: 45797374
Port 0: _______ tx_good_bytes: 38833365
