Oh, yes :)

http://wiki.osdev.org/RTL8169, seek bottom of page for the link to
http://www.magnesium.net/~wpaul/rt/RTL8110S_8169S_DataSheet_1.3.pdf,
Datasheet for the RTL8169S and RTL8110S chpsets.

So, on page #15, can see:

004Ch-004Fh R/W MPC
Missed Packet Counter: This 24-bit counter indicates the number of
packets discarded due to Rx FIFO overflow. After a s/w reset, MPC
is cleared. Only the lower 3 bytes are valid.
When any value is written to MPC, it will be reset.
