This attribute defines the number of frames (+1) to be received before an AFC frame is sent to the peer device.
For example, if this attribute is set to 2, the device will send an AFC frame back when three frames were received for the corresponding traffic class. Setting this attribute to a lower value will increase the number of AFC frames on the link. A higher value might have negative impact on the transmitter, if its own TX buffer reaches its limit as too many unacknowledged frames are stored.
As a guideline, this value should be set according to the two related buffers on each side of the link. The maximum number of frames that can be stored in the smaller buffer (peer TX or local RX) defines the upper bound for this attribute. A value at least 1 or two frames lower gives the AFC frame some time to traverse to the peer side.
