MAX_USE_THR, Input queue threshold
An incoming packet will be dropped if the number of packet
queued in a port is over the input queue threshold. This function
is always active in spite of if there is flow control or not. It is
usually higher than the threshold for flow control.
It is recommended to adopt the default value.
