Re: [dpdk-users] ixgbevf_dev_rx_init(): Set max packet length to 9600 failed.

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*/)
            };
