            Bug ID: 1050
           Summary: Burst packet receive from Mellanox gives "Segmentation
                    fault" on CQE decompression
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: omer.yamac@ceng.metu.edu.tr
  Target Milestone: ---

When I try to capture huge traffic, I got this segmentation fault. I have t=
wo
RX queue per ports. Totally I have two port and both have traffic. If the
traffic ratio is greater than 80Gbps (21Mpps), then I got the Segmentation
Fault.

I tried to check where is the error, I found that

In function `rxq_cq_decompress_v`, line 141 gives seg fault due to the null
value of elts. Also I shared a screen that includes Call Stack, elts values=
 and
seg fault.
