If link negotiation is on, a value of 1 allows the adapter to negotiate 802.3x receive flow control with the device at the other end of the link. If 802.3x flow control is supported by the other device, receive pause packets will be respected. A value of 0 disables receive flow control. The default is 1 (on).
