SUMMARY = "Container Network Interface - networking for Linux containers"
DESCRIPTION = "CNI (Container Network Interface), a Cloud Native Computing \
Foundation project, consists of a specification and libraries for writing \
plugins to configure network interfaces in Linux containers, along with a \
number of supported plugins. CNI concerns itself only with network connectivity \
of containers and removing allocated resources when the container is deleted. \
Because of this focus, CNI has a wide range of support and the specification \
is simple to implement. \
