Uh.  This seems totally bogus.  The ANAR is set to the capabilities
from the BMSR in mii_phy_auto().

I guess the real problem is that the MII code only sets "autonegotiate" if
BMCR_AUTOEN is not already set.  Perhaps it should also check to see if
the current ANAR is different from the ANAR that would be sent if we re-
started autonegotiation?

In any case, "fixing" this in the PHY reset routine when the PHY itself
has no bugs to work-around is totally inappropriate.
