[dpdk-users] DPDK l2fwd-crypto sample app Don't see encrypted icmp packet on the transmit side

[Das, Surajit]

Hi DPDK Experts,

I am running l2fwd-crypto app on SR-IOV VFs.
I am sending ICMP ping on ipv4 to the l2fwd-crypto.
On the transmit side, I am not receiving any encrypted packet.
Instead I am just receiving the very same icmp packet.
The only change I made, is to the l2fwd_mac_updating function, to set the destination mac to broadcast, to make sure the packet reaches destination VF.

Command to send packet:
arp -s 30.30.20.10 -i dev0 3a:fc:e6:60:a9:d3
ping -I dev0 30.30.20.10 -c1

Command to run l2fwd-crypto:
./l2fwd-crypto -l 0-1 -n 4 --vdev "crypto_aesni_mb0" --vdev "crypto_aesni_mb1" -w 0000:65:00.4 -w 0000:65:00.5 -- -p 0x3 --cdev SW --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

Output Counter suggests encryption was done:

What the received packet looks like:
[root at decrypt-app-deployment-79fdd95b56-h8lxr ~]# tshark  -i dev4
Running as user "root" and group "root". This could be dangerous.
Capturing on 'dev4'

Can anyone suggest what I could be missing here?
