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.
