From c3968a857a6b6c3d2ef4ead35776b055fb664d74 Mon Sep 17 00:00:00 2001 From: Daniel Walter Date: Wed, 13 Apr 2011 21:10:57 +0000 Subject: ipv6: RTA_PREFSRC support for ipv6 route source address selection [ipv6] Add support for RTA_PREFSRC This patch allows a user to select the preferred source address for a specific IPv6-Route. It can be set via a netlink message setting RTA_PREFSRC to a valid IPv6 address which must be up on the device the route will be bound to. Signed-off-by: Daniel Walter Signed-off-by: David S.
