Pull up following revision(s) (requested by msaitoh in ticket #459):

        sys/dev/mii/atphy.c: revision 1.23
        sys/dev/mii/atphy.c: revision 1.25
        sys/dev/mii/miivar.h: revision 1.69
        sys/dev/mii/mii_physubr.c: revision 1.88

s/etphy/atphy/. No functional change.

 Fix a bug that atphy(4) can't negotiate correctly when the media setting is
neither auto nor 1000baseT. Use correct index for mii_media_table[].

 History: mii_anar() is first added in OpenBSD and ported to NetBSD. On NetBSD,
only atphy(4) use this function. mii_physubr.c rev. 1.75 changed mii_anar()
for simplify. It changed the argument from the ifmedia word to ifm_data used
in our MII API, but the caller have not been changed. And then, PR kern/50206
was reported and the caller was modified by me to prevent panic but it was not
correct fix.
