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.

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.
