Improve if_fwe performance. - Simplify mbuf handling by using bulkxfer. Now, it uses mbuf clusters for RX buffer as usual ethernet drivers. - Recycle struct xfer buffer and don't call malloc at runtime. - Count input and output errors. - Handle a mbuf chain longer than 6 correctly. - Increase queue length.
