From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ulrich Weber Subject: [PATCH] ipv6: Remove IPV6_ADDR_RESERVED Date: Fri, 26 Feb 2010 10:28:58 +0100 Message-ID: <20100226092858.GA5986@babylon> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: netdev@vger.kernel.org To: davem@davemloft.net Return-path: Received: from dhost002-70.dex002.intermedia.net ([64.78.20.36]:20453 "EHLO DHOST002-70.dex002.intermedia.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S935695Ab0BZJoR (ORCPT ); Fri, 26 Feb 2010 04:44:17 -0500 Content-Disposition: inline Sender: netdev-owner@vger.kernel.org List-ID: RFC 4291 section 2.4 states that all uncategorized addresses should be considered as Global Unicast. This will remove IPV6_ADDR_RESERVED completely and return IPV6_ADDR_UNICAST in ipv6_addr_type() instead.
