Hi All,

I have some questions about the example application 'dpdk_qat'.

2) According to the doc# 328218-006, the section 18.3.2, it says we can refer to the doc# 450257,

Hello Leo_Yeh,

Thanks for your reply.

The output is inexistence on the system; the application is running on above what you provided in the screen shot.

The application is waiting to receive Ethernet packets on the Ethernet interfaces and take action depending on the "D" as is stated on the web site mentioned on our previous communications, the "D" values should be the following:

D = 0: the forwarding path is selected (the packet is forwarded out directly)

D = 1: the cryptographic path for encryption is selected (the packet is first encrypted and then forwarded out)

D = 2: the cryptographic path for decryption is selected (the packet is first decrypted and then forwarded out)

Please let us know if this information is useful to you.

Best Regards,

Carlos A.
