[NET]: Make rtnetlink infrastructure network namespace aware (v3)
After this patch none of the netlink callback support anything except the initial network namespace but the rtnetlink infrastructure now handles multiple network namespaces. Changes from v2: - IPv6 addrlabel processing Changes from v1: - no need for special rtnl_unlock handling - fixed IPv6 ndisc Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
