I'm running an Intel 82559 ethernet chip and found a minor
problem with using the eepro100 driver; they apparently
now require the CU_CMD_BASE register to be configured
before issuing a CU_STATSADDR request; I don't know
if the CU_STATSADDR request is now an offset from
CU_CMD_BASE, but the result of *not* issuing this
command is that the 82559 locks up.  The patch
is simple, move the sequence for initializing the CU_CMD_BASE
above the CU_STATSADDR command:

This diff is against 0.99B, but the same code sequence
occurs in 1.06.
