GRE tunneling on CN Pilot Routers, Epmp & 450 SMs

I see that the E400 and other APs support L2 GRE tunneling to CN Maestro. 

It would be awsome to have this supported on other Cambium CPE devices like the CNPilot Routers, Epmp and 450 SMs!

It would be a great feature and selling point for the whole line! making easier to do L2 tunneling over a Cambium Network!

If ePMP devices will support GRE termination on 3rd party gateway It will be useful for us also.

GRE tunnel termination from pmp450 sm's would be pretty cool, so would vxlan but that would require different hardware.
