This register is used to calculate the congestion factor of the CPU
port, that is the quotient of the accumulated byte count of the CPU
output queue to the specified CPU port speed. While the congestion
control is triggered, the output ports with congestion factor larger
than the average will enter into the congestion control mode.

The congestion factor, i.e. the quotient of the accumulated byte
count of the output queue to the port speed, for each of 16 Ethernet
ports is calculated by the flow control module. While the congestion
control is triggered, the output ports with congestion factor larger
than the average will enter into the congestion control mode.
