Hello,
I have a standalone utility that implements
ICMP ping over DPDK.
When I run the utility with i40e PMD over VF it stacks with the following output and never recovers.
The last reported tx_tail value was 4095. TX queue length in that run was 4096
The fault was reproduced on several Dell PowerEdge R630 servers
My environment:
DPDK 16.11 + 6809e62e555c7b36d248a0e8086e3c3bbbb87a37 (net/i40e: enable VF MTU change)
i40e: version: 1.5.25, firmware-version: 5.04 0x80002537 0.0.0
Regards,
Gregory

Update
The fault is relevant to VF only
DPDK over i40e PF functions correctly

Gregory

Mbufs are not being freed inside the ring fast enough to accommodate
the incoming traffic.
