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: Port statistics ==================================== Statistics for port 0 ------------------------------ Packets sent: 1 Packets received: 0 Packets dropped: 0 Statistics for port 1 ------------------------------ Packets sent: 0 Packets received: 1 Packets dropped: 0 Crypto statistics ================================== Statistics for cryptodev 0 ------------------------- Packets enqueued: 0 Packets dequeued: 0 Packets errors: 0 Statistics for cryptodev 1 ------------------------- Packets enqueued: 1 Packets dequeued: 1 Packets errors: 0 Aggregate statistics =============================== Total packets received: 1 Total packets enqueued: 1 Total packets dequeued: 1 Total packets sent: 1 Total packets dropped: 0 Total packets crypto errors: 0 ==================================================== What the received packet looks like: [root@decrypt-app-deployment-79fdd95b56-h8lxr ~]# tshark -i dev4 Running as user "root" and group "root".

[ETHERNET FRAME CHECK SEQUENCE INCORRECT] ^C1 packet captured Can anyone suggest what I could be missing here? Regards, Surajit
