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
