I am running dpdk-stable-18.11.8 on Centos 7, targeting an Intel X722 NIC. I want ipv4 and udp header checksums to be calculated by hardware, so I set the device configuration to:
struct rte_eth_conf local_port_conf; memset(&local_port_conf, 0, sizeof(struct rte_eth_conf)); local_port_conf.rxmode.split_hdr_size = 0; local_port_conf.txmode.mq_mode = ETH_MQ_TX_NONE; local_port_conf.txmode.offloads = DEV_TX_OFFLOAD_OUTER_UDP_CKSUM | DEV_TX_OFFLOAD_OUTER_IPV4_CKSUM; rte_eth_dev_configure(0,1,1,&local_port_conf); rte_eth_dev_configure returns: 0xffffffea (-22) Does this mean that DPDK 18.11 doesn't support checksum offload to the X722 NIC?
