Thank you for the quick reply. I will do that testing tonight, when internet access going down for a bit won't be a problem. Right now I was learning about how the various components work together, and I think this problem has to do with the Ethernet phy, not the Ethernet interface. The mii-tool program, available via opkg, provides more information about the phy:
# mii-tool -v -v -v -v eth1
eth1: negotiated 100baseTx-FD, link ok
registers for MII PHY 4:
3100 796d 004d d041 0101 c1e1 000d 2801
0000 0000 1000 0000 0000 0000 0000 2000
0862 7c10 0000 1002 002c 0000 0000 0000
3200 0000 0000 0000 0000 0000 824e 0000
product info: vendor 00:13:74, model 4 rev 1
basic mode: autonegotiation enabled
basic status: autonegotiation complete, link ok
capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
The eth0 port which goes to the switch chip does not have a phy.
