I attempted to reproduce this on a TS-7300 with the default shipping 
kernel. I found I was able to ping the second ethernet port(eth1) 1000 
times without any dropped packets. I also did not see the time increase 
as the number of packets increased.

If you are still having this problem can you provide more information so 
I can attempt to reproduce it?
