• Manufacturer Part Number: bcm5708c
• Description: Bcm5708c - 10/100/1000base-t Toe Pci Express Ethernet Controller
• Manufacturer: Broadcom Corp.

The BCM5708C provides a fully integrated Layer 4 and Layer 5
solution—TCP/IP, RDMA, and iSCSI 1.0 along with a complete 10/100/
1000BASE-T Gigabit Ethernet, IEEE 802.3™ compliant media access
control (MAC), and physical layer transceiver solution for high-
performance network applications. By itself, the BCM5708C provides a
complete single-chip Gigabit Ethernet NIC with a TCP/IP processing
engine, RDMA NIC (RNIC), iSCSI 1.0 HBA, or LOM solution.
The BCM5708C 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 BCM5708C
processes the frame up to the highest layer supported present in it. For
example, the BCM5708C processes the frame for RDMA when the
frame is an RDMA frame.
With the appropriate configuration, the BCM5708C can simultaneously
support the following three functions:
• RDMA network interface controller (RNIC)
• iSCSI host bus adapter
• TOE chimney-enabled network accelerator
