Hi All -
I have server with Intel QAT c62x device.  I followed all documentation.

-        Rebuild DPDK to use QAT

-        QAT drivers are loaded.

-        QAT devices are bound to DPDK


Crypto devices using DPDK-compatible driver
===========================================

0000:3d:02.2 'Device 37c9' drv=igb_uio unused=qat_c62xvf,vfio-pci

But if I use l2fwd-crypto sample, I get no crypto device found error

Checking link statusdone
Port0 Link Up. Speed 1000 Mbps - full-duplex
Port1 Link Up. Speed 1000 Mbps - full-duplex
Lcore 0: RX port 0
Lcore 1: RX port 1
No crypto devices available
EAL: Error - exiting with code: 1
  Cause: Failed to initialize crypto devices

It works if I add  virtual device --vdev "crypto_aesni_mb0" but I am not able to use HW device.
Your help is appreciated.

Thanks
Pravin
