Configure Pause

As defined by the IEEE 802.3x specification, PAUSE is a simple stop-start form of flow control. A device can temporarily halt incoming data by sending a PAUSE frame, which is a parameter indicating the length of time the sender should wait before sending additional data.

If enabled, the EVIC port issues a PAUSE command across the Ethernet port when the number of receive buffers currently posted to the MAC falls below a predetermined value. The PAUSE condition is relieved when the number of receive buffers currently posted to the MAC exceeds this predetermined value. An EVIC port will always react to a received PAUSE command.
