Intel® IXF1104 4-Port Gigabit Ethernet Media Access Controller

packets have a valid preamble and SFD, but have a bad CRC, or are either shorter than 64 octets or longer than 1518 octets.

5.1.8.2Advantages

The following lists additional IXF1104 MAC registers that support features not documented in RMON:

•MAC (flow) control frames

•VLAN Tagged

•Sequence Errors

•Symbol Errors

•CRC Error

These additional counters allow for differentiation beyond standard RMON probes.

Note: In fiber mode, a packet transfer with an invalid 10-bit symbol does not always update the statistics registers correctly.

•Behavior: The IXF1104 MAC 8B10B decoder substitutes a valid code word octet in its place. The packet transfer is aborted and marked as bad. The new internal length of the packet is equal to the byte position where the invalid symbol was. No packet fragments are seen at the next packet transfer.

•Issue: If the invalid 10-bit code is inserted in a byte position of 64 or greater, expected RX statistics are reported. However, if the invalid code is inserted in a byte position of less than 64, expected RX statistics are not stored.

5.2SPI3 Interface

The IXF1104 MAC SPI3 Interface is implemented to the System Packet Interface Level 3 (SPI3) Physical Layer Interface standard. The interface function allows the IXF1104 MAC blocks to interface to higher-layer network processors or switch fabric.

The IXF1104 MAC transmit interface allows data flows from a network processor or switch fabric device to the IXF1104 MAC. The receive interface allows data to flow from the IXF1104 MAC to the network processor or switch fabric device.

This interface receives and transmits data between the MAC and the Network Processor with compliant SPI3 interfaces. The SPI3 interface operation is defined in the OIF-SPI3-01.0 (available from the Optical Internet Working Forum [www.oiforum.com]). The OIF specification defines operation for the transfer of data at data rates of up to 3.2 Gbps when operating at a frequency of 104 MHz. The IXF1104 MAC defines operation for the transfer of data at data rates of up to 4.256 Gbps when operating at a maximum frequency of 133 MHz in MPHY mode and 125 MHz in SPHY Mode.

There is no guarantee of the number of bytes available since the size of packets is variable. An IXF1104 MAC port-transmit packet available status is provided on signals DTPA, STPA or PTPA, indicating the TX FIFO is nearly full.

In the receive direction, RVAL indicates if valid data is available on the receive data bus and is defined so that data transfers can be aligned with packet boundaries.
