Hi, I configured my own DPDK-based application to support jumbo frames: - port_conf.rxmode.jumbo_frame = 1 - port_conf.rxmode.max_rx_pkt_len = 9600 After this configuration I can receive jumbo packets but I can not transmit those packets. Can somebody help me please? - DPDK version: 17.05.2 - NIC: Intel 82599 - Driver: ixgbe Thanks, MRP
