However when we set maximum packet length to be: port_conf.rxmode.max_rx_pkt_len =3D RTE_ETHER_MAX_LEN; and do not set the rx offload flags then the DPDK card mlx5 driver reports error files and reports packet loss. It seems that when jumbo are not configured in DPDK but present in the network, the driver/card is failing. I have 85MB of compressed debug files from mlx5 driver that I can share. here is the first line in the debug files: =3D=3D> dpdk_mlx5_port_1_rxq_1_1099615000 <=3D=3D Unexpected CQE error syndrome 0x34 CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 47611 rq_ci =3D 38111 cq_ci =3D 1318495 =3D=3D> dpdk_mlx5_port_1_rxq_1_1108098344 <=3D=3D Unexpected CQE error syndrome 0xe9 CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 0 rq_ci =3D 32768 cq_ci =3D 822834 =3D=3D> dpdk_mlx5_port_1_rxq_1_1365813620 <=3D=3D Unexpected CQE error syndrome 0xb0 CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 55537 rq_ci =3D 38963 cq_ci =3D 709664 =3D=3D> dpdk_mlx5_port_1_rxq_1_1370939994 <=3D=3D Unexpected CQE error syndrome 0xcf CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 20208 rq_ci =3D 55008 cq_ci =3D 762646 =3D=3D> dpdk_mlx5_port_1_rxq_1_1383113394 <=3D=3D Unexpected CQE error syndrome 0xdb CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 26607 rq_ci =3D 32768 cq_ci =3D 978768 =3D=3D> dpdk_mlx5_port_1_rxq_1_149947326 <=3D=3D Unexpected CQE error syndrome 0xe2 CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 6862 rq_ci =3D 32768 cq_ci =3D 1018398 =3D=3D> dpdk_mlx5_port_1_rxq_1_1614261196 <=3D=3D Unexpected CQE error syndrome 0xe7 CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 39098 rq_ci =3D 32768 cq_ci =3D 555823 =3D=3D> dpdk_mlx5_port_1_rxq_1_1632566952 <=3D=3D Unexpected CQE error syndrome 0x9a CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 12891 rq_ci =3D 38780 cq_ci =3D 1024427 =3D=3D> dpdk_mlx5_port_1_rxq_1_1651330084 <=3D=3D Unexpected CQE error syndrome 0x74 CQN =3D 3304 RQN =3D 12583234 wqe_counte= r =3D 7765 rq_ci =3D 32768 cq_ci =3D 40533 --=20 You are receiving this mail because: You are the assignee for the bug.=
