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.
