[L Nageshwar L]

Hi,
I am using Mellanox Technologies MT27520 Family card and it is not recognized by DPDK test program.
When I run the l2fwd binary, I got the below error.
Please guide me how to solve the issue.

I am using DPDK-1.6.0r2 version.


# ./build/l2fwd -c 3 -n 2 --huge-dir /mnt/huge -m 4096 -b 0000:01:00.0 -b 0000:01:00.1 -b 0000:01:00.2 -b 0000:01:00.3 -b 0000:00:19.0 -- -p 3
