[dpdk-users] IPSEC-SECGW sample application

Hi Avi,

 My response inline.

The SA rule "type" field lets you choose the kind of offload. 
Following is the description from the ipsecgw app guide:

<type>

Action type to specify the security action. This option specify the SA to be performed with look aside protocol offload to HW accelerator or protocol offload on ethernet device or inline crypto processing on the ethernet device during transmission.
Optional: Yes, default type no-offload
Available options:
lookaside-protocol-offload: look aside protocol offload to HW accelerator
inline-protocol-offload: inline protocol offload on ethernet device
inline-crypto-offload: inline crypto processing on ethernet device
no-offload: no offloading to hardware

Correct your SA rules to have the desired "type" field.

The ipsecgw application must work fine for QAT PCIe as well as Ethernet NIC with IPSec feature provided the VFs as correctly bound to DPDK.

 The ipsecgw application must work fine for QAT PCIe as well as Ethernet NIC with IPSec feature provided the VFs as correctly bound to DPDK. 
Please try running a more basic L2Fwd Crypto application on your NIC to make sure the Crypto feature works.
