I've had similar issue with Intel Ethernet controllers (i82562ET and i82801BA/BAM). It was practically no load, and on the wire there was no duplicates but ping got duplicates anyway. - It only happens sporadically and it happens to about 10 boxes with the same FreeBSD version (exact same). Havent had the chance to dig into it though.... Same with you?

In particular the linksys pcmcia cards seem to do this. In my testing and analysis this always seems to occur when the card is busy and what happens is you lose some packet and another appears to be duplicated... I traced this out with ethereal a while ago and then just stopped using that card when I figured out it was some sort of circular buffer issue.. I did not dig in and find out if it was the card or driver... I rather suspect it is the card (since it is a low end one).. but one never knows... R -- Randall R.
