- Extending SONiC building infrastructure to provide users
with greater flexibility, by allowing them to elect a
routing-stack different than the default one (quagga). The desired
routing-stack will be defined in rules/config file.
- As part of these changes I'm adding support for
Free-Range-Routing (FRR) stack. Quagga will continue to be
the default routing-stack.
