Data Transmission Not Resumed Immediately When 10GbE MAC Receives PFC Frame

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.
