The number of checksum errors seems okay and doesn't really change when
I plug in the second network connection, but the ring buffer usage still
increases dramatically.

Stats look OK.  BTW, tx/rx_packets_csum is not a number of checksum 
errors, that's a number of packets where driver used hw checksum 
acceleration :).

Ah, silly me.  Can you tell me where I can find the number of received
packets with bad ethernet checksums?  I'm still thinking that I might
have a little hardware problem that is increasing the bit error rate
when I use both ports, ultimately increasing my buffer utilization.
