Hi,
I get a crash when I put a significant amount of load on ConnectX-4/mlx5,
i.e., 50Gbps for 100GbE port.
Thread 22 "lcore-slave-19" received signal SIGSEGV, Segmentation fault.

My environments are:
Ubuntu 18.04.2 LTS 4.15.0-50-generic
MLNX_OFED_LINUX-4.5-1.0.1.0-ubuntu18.04-x86_64
fw_ver: 12.17.2020
vendor_id: 0x02c9
vendor_part_id: 4115
hw_ver: 0x0
board_id: LNR3270110033
DPDK 18.11.2
It looks like the CQE compression is the crashing place.
dpdk-stable-18.11.2/drivers/net/mlx5/mlx5_rxtx_vec_sse.h:956
953 /* Decompress the last CQE if compressed. */
954 if (comp_idx < MLX5_VPMD_DESCS_PER_LOOP && comp_idx == n) {
955 assert(comp_idx == (nocmp_n % MLX5_VPMD_DESCS_PER_LOOP));
956 rxq_cq_decompress_v(rxq, &cq[nocmp_n], &elts[nocmp_n]);
And I'm wondering how I can disable rxq_cqe_comp_en devargs.
<https://doc.dpdk.org/guides-18.02/nics/mlx5.html>
22.5.3. Run-time configuration
rxq_cqe_comp_en parameter [int]
Any information or guesses are appreciated.
Best regards,
Yasu
