3.2.3.1. LL 40GbE IP Core RX Filtering

The LL 40GbE 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.
