We are testing Strongswan with  IoT-LS1021-SDK-V0.1, as there is a lot of compiling missing header files issue in the default SDK with strongswan_5.1.3, we move to Strongswan 5.2.3 which got from here meta-networking/recipes-support/strongswan · 1dbb1ff9b15e42ace9ac12c8e0630b9e520e17cd · yocto / meta-openembedded · GitL…  

Now we can get StrongSwan running without a problem. but when try to testing its performance with  Iperf, we always got the following issue, prompted it is a kernel bug
