Preamble Pass-through Mode Does Not Work with PFC Frames

Description

Low Latency Ethernet 10G MAC designs with Enable preamble pass-through mode and Enable priority-based flow control (PFC) options turned on, will produce incorrect data or pause frames when the pause frames and data frames interleave.

Limitation

Do not turn on both the Enable preamble pass-through mode and Enable priority-based flow control (PFC) options together. You can turn either one option but not both options together.

This issue is fixed in version 14.0 of the Low Latency Ethernet 10G MAC.
