DESCRIPTION
"Flow control configuration.
Flow control is used to throttle the throughput rate of an
end station to avoid dropping packets during network
congestion. If flow control mode is not set and if there is
no packet buffer space available, the incoming packets are
discarded.
Symmetric Flow Control stops and restarts packet transmission
by transmitting and receiving pause frames. When a port's
free buffer space is almost empty, the device send out a Pause
frame to stop the remove node from sending more frames into
the switch. When congestion on the port is relieved, the device
send out a Pause frame with pause time equal to zero, making
the remove node resume transmission."
