3.2.3.9. Pause Ignore

If you turn on flow control by setting Flow control mode to the value of Standard flow control or Priority-based flow control in the LL 100GbE parameter editor, the IP core processes incoming pause frames by default. However, when the pause frame receive enable bit (for standard flow control) or bits (for priority-based flow control) is or are not set, the IP core does not process incoming pause frames. In this case, the MAC TX traffic is not affected by the valid pause frames.

If you turn off flow control by setting Flow control mode to the value of No flow control in the LL 100GbE parameter editor, the IP core does not process incoming pause frames.
