Dynamic threshold management: Bit[13]: The add bit. Bit[12:8]: The offset bits.When Bit[13] = 1, the switch will
use the value (buffers really used + 8*bit[12:8]) as the buffer count that the switch has used.When Bit[13] = 0, the
switch will use the value (buffers really used - 8*bit[12:8]) as the buffer count that the switch has used.Fixed
threshold management:Bit[13]: This bit doesn't affect the threshold.Bit[12:8]: The total buffer threshold bits.
