// 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.
