Add the new fcoe_transport.c file that implements basic fcoe transport interface. Eventually, the sysfs entries to create/destroy/enable/disable an FCoE instance will be coming to the fcoe transport layer, who does a look-up to find the corresponding transport provide and pass the corresponding action over to the identified provider. The fcoe.ko will become the default fcoe transport provider that can support FCoE on any given netdev interfaces, as the Open-FCoE.org's default software FCoE HBA solution. Any vendor specific FCoE HBA driver that is built on top of Open-FCoE's kernel stack of libfc & libfcoe as well as the user land tool of fcoe-utils can easily plug-in and start running FCoE on their network interfaces. The fcoe.ko will be converted to act as the default provider if no vendor specific transport provider is found, as it is always added to the very end of the list of attached transports.
