Resetting an Arduino Ethernet

Does anyone know if the W5100 chip on an Arduino Ethernet can be reset in software? You can mess around bending pins with an Ethernet shield, but the Arduino Ethernet doesn't have that option, and when the W5100 goes out to lunch it seems to stay there.

Thanks - Will

I see:

W51_write(W5100_MR, W5100_MR_SOFTRST);
