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.

currently not an option.
