By itself, the BCM5708S provides a complete single-chip Gigabit Ethernet NIC with a TCP/IP Offload Engine, RDMA NIC (RNIC), iSCSI HBA, or LOM solution. SMB Interface SFLASH Control SFLASH Interface Target Applications of the BCM5708S • • • • The BCM5708S is different from other network controllers because it can process the TCP/IP and relevant L5 protocols on data directly from the application buffers on the host, thereby relieving the host CPU from these time-consuming operations. On the receive path, the BCM5708S processes the frame up to the highest layer supported present in it, for example, the BCM5708S processes the frame for RDMA when the frame is an RDMA frame.
