[dpdk-users] Using l2fwd-crypto sample app

["Das, Surajit" <Surajit.Das@commscope.com>]

Hi DPDK Experts,

We are working on expanding our DPDK application to do IPSec based encryption.
To that end I was trying out the sample application provided.
But, I am hitting an error which is probably configuration related.

My DPDK version:
dpdk-stable-19.11.5
OS: CentOS Linux release 7.7.1908 (Core)
Kernel: 3.10.0-1062.el7.x86_64

Command run with options and output:
./l2fwd-crypto -l 0-1 -n 4 --vdev "crypto_aesni_mb0" --vdev "crypto_aesni_mb1" -- -p 0x3 --chain CIPHER_HASH --cipher_op ENCRYPT --cipher_algo aes-cbc --cipher_key 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f --auth_op GENERATE --auth_algo aes-xcbc-mac --auth_key 10:11:12:13:14:15:16:17:18:19:1a:1b:1c:1d:1e:1f
EAL: Detected 8 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: failed to parse device "crypto_aesni_mb0"
EAL: Unable to parse device 'crypto_aesni_mb0'
EAL: Error - exiting with code: 1
  Cause: Invalid EAL arguments


I am not sure what is causing the error failed to parse device "crypto_aesni_mb0"
Is there a specific driver that needs to be loaded? Or is there a hardware dependency?
I am using virtio nic to test out the app.
Please suggest if the info I have provided is sufficient to determine the cause?
