I just installed SL for the first time on an Intel Core Duo box with an 
MSI G965M-FIR motherboard. This board has a Realtek RTL-8169SC network 
inteface that uses the r1000 driver.  Pings show a bizarre pattern.  If I 
ping every 10 seconds, the turnaround time gradually increases with each 
ping until it hits about 2 seconds, at which point it drops back to a low 
value and starts climbing again.  If I ping every second, I see the 
increasing behavior also, with every other ping taking an extra second.

Any clues?
