This change introduces a package that provides basic functions for the manipulation of logical network interfaces, interface addresses and data links on Solaris. As BSD variants implement routing socket and routing messages, Linux implements netlink socket and netlink messages, Solaris implements STREAMS-like interface for reading, writing network facility information inside the kernel. The package wraps various I/O control calls which involve message exchanges between kernel protocol modules in exposed APIs. At present, the package supports Solaris 11 or above. Updates golang/go#7177. Change-Id: I192d85e53b0bee942dfefca0f73a3eb94ab8bfe9 Reviewed-on: https://go-review.googlesource.com/29893 Reviewed-by: Ian Lance Taylor <iant@golang.org>
