Hi all,


I have already set up 2 VFs on enslf1 NIC. The DPDK version is dpdk-stable-19.11.7. There is one issue related to max packet length to 9600.
I tried both igb_uio and VFIO_PCI as driver. Could you kindly guide me how to fix this issue?

Actually, the Jumbo frame is enanbled during . What could be the reason for failure to set max package length to 9600 bytes?
    struct rte_eth_rxmode rxmode =
            { .split_hdr_size = 0,
              .max_rx_pkt_len = MAX_RX_LEN,
              .offloads=(DEV_RX_OFFLOAD_JUMBO_FRAME /*|DEV_RX_OFFLOAD_CRC_STRIP*/)
            };

One more info. 
This issue is not observed by PF directly but can be observed by VFs. 
I am blocked by this error.  May I get some help about this issue? Thanks a lot.
