Rare project developers

[Frédéric LOUI <>]

We also talked about getting back to p4lang/bmv2 in order to clarify the 
possibility to access via P4Runtime GRPC interface the mathematical function 
(extern library ?)

And also a tangible interest from Moises to implement a central controller. 
(mc36 suggested to use PCEP which is perceived as IETF way to handle 
centralise TE)
