Patch from Lars Kellogg-Stedman:

    Erik, et al.

    The attached patch makes the following changes to networking/ifupdown.c:

    (1) It swaps all calls to 'ip link set' and 'ip addr set'.  This solves
    two problems:

      (a) Calling 'ip link set <dev> up' before assigning an address
      generates an error message, and

      (b) Under User Mode Linux, running in with ethernet interfaces
      in daemon mode, the MAC address for an interface is selected
      based on the IP address assigned to that interface.  If the
      interface is brought up before being assigned an IP address,
      it gets a null MAC.

    (2) It further cleans up run_mapping().

    This patch is against ifupdown.c revision 1.25.
