Environment

    Quartus® II Subscription Edition
    Ethernet
BUILT IN - ARTICLE INTRO SECOND COMPONENT

Critical Issue

Description

When the 10GbE MAC receives a PFC frame with the instruction to resume data transmission on priority queue n, the MAC does not deassert the avalon_st_rx_pfc_pause_data[n] signal immediately and the data transmission on priority queue n does not resume immediately.

This issue affects all 10GbE MAC designs with the PFC enabled.

Resolution

No workaround.

This issue will be fixed in a future version of the 10-Gbps Ethernet MAC MegaCore function.
