Flow Control
The Flow Control property allows you to enable or disable the receipt or 
transmission of PAUSE frames which allow the adapter and the switch to 
control the transmit rate. The port side that receives the PAUSE frame 
momentarily stops transmitting. The recommended selection is Disable, 
which configures the adapter to ignore PAUSE frames. By default, the 
Flow Control property is disabled. 
To change the Flow Control property, do the following:
