Hi Team,
When I set the value to MAX_MBUF_SIZE as less than 16256, all the
initialization went through fine and the application was online.
But when I increase the MAX_MBUF_SIZE to more than 16256 like 16257, 17000,
or 18000, I get the attached log error which shows an issue in configuring
the virtual queues for the NIC.
Log Snip:
i40evf_configure_vsi_queues(): Failed to execute command of
VIRTCHNL_OP_CONFIG_VSI_QUEUES
i40evf_dev_start(): configure queues failed
MTU size for port id: is: 9000
Failed to start the fast pkt for port_id : 1Ret: -1
Some Observations:
1. Thought memory availability was an issue, so provided 10x more memory
and allocated 10x huge pages than required, still noticed the same issue.
2. Got to know MTU size also plays a role in deciding the mbuf_size, so
tried running app with MTU of less value, but still issue persists.
Please someone enlighten me on what is happening here.
Thanks

Added net/i40e driver maintainers.
This error indicates a failure either when sending a message to the PF
driver, or that the PF driver refused to configure this VF with the
passed parameters.
Assuming you are using the PF i40e driver, I tracked this message
handling to find that buffer size is limited (the exact limit is not
clear to me) probably due to some hw limitations.
See:

/* max pkt. length validation */
if (info->max_pkt_size >= (16 * 1024) || info->max_pkt_size < 64) {
ret = -EINVAL;
goto error_param;
}
I'll let net/i40e reply with better details/explanations.

Hi,
Which DPDK version did you use?
As i40evf PMD has been deprecated for long time.
