Subject: [PATCH iproute2 0/2] iplink: Fix link-netns handling

When handling something like:

    # ip -n ns1 link add netns ns2 link-netns ns3 link eth1 eth1.100 type vlan id 100

should lookup eth1 in ns3 and set IFLA_LINK_NETNSID to the id of ns3 from ns2.
But currently ip-link tries to find eth1 in ns1 and failes. This series fixes
it.

  ip: Move of set_netnsid_from_name() to namespace.c
  iplink: Fix link-netns id and link ifindex
