        Add ldmvsw.c driver
      
        Details:
      
        The ldmvsw driver very closely follows the sunvnet.c code and makes
        use of the sunvnet_common.c code for core functionality.
      
        A significant difference between sunvnet and ldmvsw driver is
        sunvnet creates a network interface for each vnet-port *parent*
        node in the MD while the ldmvsw driver creates a network interface
        for every vsw-port node in the Machine Description (MD).
        Therefore the netdev_priv() for sunvnet is a vnet structure while
        the netdev_priv() for ldmvsw is a vnet_port structure.
      
        Vnet_port structures allocated by ldmvsw have the vsw bit set.
        When finding the net_device associated with a port, the common code keys
        off this bit to use either the net_device found in the vnet_port or the
        net_device in the vnet structure (see the VNET_PORT_TO_NET_DEVICE() macro in
        sunvnet_common.h). This scheme allows the common code to work with
        both drivers with minimal changes.
      
        Similar to Xen, network interfaces created by the ldmvsw driver will always
        have a HW Addr (i.e. mac address) of FE:FF:FF:FF:FF:FF and each will be
        assigned the devname "vif<cfg_handle>.<port_id>" - where <cfg_handle> and
        <port_id> are a unique handle/port pair assigned to the associated
        vsw-port node in the MD.
