I once tried to capture traffic with an r8169. I gave up very quickly, 
and fitted a Pro-1000 card. I think at first I jammed a server card in 
the 32-bit slot in the machine I had, and it worked, until a few 1000-MT 
desktop cards arrived. It made a huge difference on the test hardware we 
had.

I'm successfully capturing 5 minute averages in excess of 500Mb @~ 
80kpps on a PE1850, in 32 bit mode, on an 82541 Intel GE, using ring 3.7.7.

# cat /proc/net/pf_ring/info
Version             : 3.7.7
Bucket length       : 1514 bytes
Ring slots          : 8192
Slot version        : 9
Capture TX          : No [RX only]
IP Defragment       : No
Transparent mode    : No
Total rings         : 2
Total plugins       : 0
