On LS2085 platform, the basic networking product performs autonomous IP forwarding and IPSEC on the AIOP, data path functions run mostly independent of the GPP software and only involve GPP when necessary.
NADK(Network Acceleration Development Kit) is a complete user space development kit for networking applications.
This IPSEC application is implemented in Linux user space using NADK framework, this application learns the Linux configuration through the netlink event notification and sends the configuration to AIOP DP using the respective NF APIs. The application invokes NF APIs to send configuration details to IPsec data path on the AIOP.
