[dev] Conditions to have code accepted into the project

Dear all, We have an implementation of the LISP protocol and we are evaluating how easy would be to adapt it to be integrated in the FRRouting project. Our initial code has its own memory management, timers (task scheduling), ... In order to know how much of the code can be reused, I would like to know if it is really mandatory to use the memory management library provided by the FRRouting project or the task scheduling (for instance to send periodic control messages) to have the code accepted and merged in the FRRRouting project. Another question we have is that our code is licensed under Apache 2. Is FRRouting license compatible with apache 2 ? I believe yes but I am not sure. Best regards Albert López
