instead of discrete function pointers, and extend this to include
a "reset" entry point. Make sure any PHY-specific reset routine is
always used, and provide one for the LXT-970 which disables MII
interrupts (as is done for a few other PHYs we have drivers for).
on several inexpensive 10/100 Ethernet boards (e.g. D-Link DFE-530TX,
Winbond 10/100 boards), and is also the built-in PHY on the DM9102
10/100 Ethernet chip.
