[dpdk-dev] BraodCom BNXT driver - Sample program crash DPDK - 18.11

[vikram T]

Hi,
I am trying to run the sample program "hello_world" using the DPDK - 18.11
version on Braodcom BNXT driver the crash is seen:

[root at localhost build]# ./helloworld

Segmentation fault

The same crash is also seen on DPDK-19.05 version.
However with DPDK-17.05 version the sample program runs perfectly fine.

Below is the output of dpdk-devbind.py -s

Can you help to find the reason for the crash.
