NetBSD/sys/dev/ic/rtl80x9.c
is d8bf2eb8ef - we didn't write enable toe config1-3 registers before trying to set the
media.
- read out original settings to find out what the defaults (EEPROM) for this
  board were, instad of hardwiring to auto.
XXX the first might need further refinement. At least on my boards, 10baseT
doesn't work for 10baseT, only AUTO.
