[dev] Conditions to have code accepted into the project

Our implementation have an initial support of netconf to configure the 
deamon. It would be acceptable to have our daemon (Apache 2) configured 
through FRR using netconf?
As an initial step our intention is only support LISP MS/MR (only 
control plane functionalities)

Best regards
