The mechanisms to process flow control frames from the Ethernet link are specific to the flow control mode of the LL 100GbE IP core. Performance and Resource Utilization 1 Therefore, control frames that are inappropriate to the IP core mode, simply pass through the RX MAC to the RX client interface.

3.2.3.5. LL 100GbE IP Core Malformed Packet Handling

The LL 100GbE IP core processes all incoming valid frames. However, the IP core does not forward pause frames to the Avalon-ST RX client interface by default. If you set the cfg_fwd_ctrl bit of the RX_PAUSE_FWD register to the value of 1, the IP core forwards pause frames to the Avalon-ST RX client interface. 3.2.1. LL 100GbE IP Core TX Datapath 3.2.2.

Differences Between Low Latency 40-100GbE IP Core and 40-100GbE

The LL 100GbE IP core provides two different client interfaces: the Avalon-ST interface and a custom interface. Custom streaming interface (no adapters): Data bus width is 256 bits. The LL 40-100GbE IP core can support full wire line speed with a 64-byte frame length and back-to-back or mixed length traffic x 1 with no dropped packets. For a detailed specification of the Ethernet protocol refer to the IEEE 802.3ba-2010 High Speed Ethernet Standard. Reduced Bandwidth With Left-Aligned SOP Requirement Illustrates the reduction of bandwidth that would be caused by left-aligning the SOP for the LL 100GbE IP core.
