From f1a89a118299df9e5afbaaedf83e5709a28632b6 Mon Sep 17 00:00:00 2001 From: Chuck Lever <chuck.lever@oracle.com> Date: Tue, 12 Jan 2010 17:41:10 -0500 Subject: [PATCH] SUNRPC: Deprecate support for site-local addresses RFC 3879 "formally deprecates" site-local IPv6 addresses. We interpret that to mean that the scope ID is ignored for all but link-local addresses.
