Missed Packet Count Register (MPCNT)
The MPCNT keeps the number of packets that were dropped due to various types of receive errors.
The MPCNT is a read clear register. In addition, S/W also can write an initial value to MPCNT and the
missed packet counter will start counting from that initial value. If the missed packet counter is
overflow, the MMP of MISTA will be set.
