            Bug ID: 42
           Summary: Crypto_mrvl error with multiple instances
           Product: DPDK
           Version: unspecified
          Hardware: ARM
                OS: Linux
            Status: CONFIRMED
          Severity: major
          Priority: Normal

  Target Milestone: ---

Hi,
We are using DPDK over Marvell ARMADA 8040 processor and we have used all t=
he
MUSDK patches provided, to make our DPDK stack work.

But we are facing an issue while trying to use L2FWD-Crypto test applicatio=
n.
Here we are trying to use crypto_mrvl with two instances and we are getting
error on second one.
The command used is:
./l2fwd-crypto  -c 0x3 -n 4 --vdev=3Dnet_ring,iface=3Deth1,iface=3Deth0
--vdev=3Dcrypto_mrvl0 --vdev=3Dcrypto_mrvl1 -- \
  --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 sha1-hmac \
  --auth_key 10:11:12:13:14:15:16:17:18:19:1a:1b:1c:1d:1e:1f

While executing this, we are getting the errors:
[ERROR] Engine #0: Ring #0 is busy. Active rings map is 0x1
Failed to setup queue pair 0 on cryptodev 1EAL: Error - exiting with code: 1
  Cause: Failed to initialize crypto devices=20


Can you please let us know if you see any issue is above command line being
used.
In addition, can we use multiple instances for single crypto engine support=
ed
by Armada 8040?

Regards,
Akhil
