I am a bit stumped= in tracking it down, any help is greatly appreciated! We are using the 82599 NIC & DPDK 1.3 (with RSC disabled). Settings: /* Ethernet Configuration */ static struct rte_eth_conf port_conf =3D { .rxmode =3D { .split_hdr_size =3D 0, .header_split =3D 0, /**< Header Split disabled */ .hw_ip_checksum =3D 1, /**< IP/UDP/TCP checksum offload enabled. */ .hw_vlan_filter =3D 0, /**< VLAN filtering disabled */ .jumbo_frame =3D 0, /**< Jumbo Frame Support disabled */ .hw_strip_crc =3D 1, /**< CRC stripped by hardware */ }, .rx_adv_conf =3D { .rss_conf =3D { .rss_key =3D NULL, .rss_hf =3D 0x00, }, }, .txmode =3D { }, }; Thank you, Bryan Benson Amazon Web Services
