* CNI: bump to 1.0.1 This commit bumps the declared version of CNI in the Kilo manifests to 1.0.1. This is possible with no changes to the configuration lists because our simple configuration is not affected by any of the deprecations, and there was effectively no change between 0.4.0 and 1.0.0, other than the declaration of a stable API. Similarly, this commit also bumps the version of the CNI library and the plugins package. Bumping to CNI 1.0.0 will help ensure that Kilo stays compatible with container runtimes in the future.

// Package netlink provides a simple library for netlink. Netlink is

|
// the interface a user-space program in linux uses to communicate with
|
|
// the kernel. It can be used to add and remove interfaces, set up ip
|
|
// addresses and routes, and confiugre ipsec. Netlink communication
|
|
// requires elevated privileges, so in most cases this code needs to
|
|
// be run as root. The low level primitives for netlink are contained
|
|
// in the nl subpackage. This package attempts to provide a high-level

// interface that is loosly modeled on the iproute2 cli.
