  SVN rev 196367 on 2009-08-18 20:25:02Z by yongari
  
  MFC r196366:
    Backout r193289. r193289 restored page select bits to previous
    value instead of blindly resetting it to 0. However, it seems page
    select bits of some 88E1116 PHY is initialized to invalid one such
    that restoring page select bits after programming broke MII
    register access. The correct solution would be reset page select
    bits to 0 in PHY attach stage but it would require more testing.
    Since we're in BETA stage such a change would be dangerous so just
    back it out.
    This change should fix nfe(4) breakage on NVIDIA MCP55.
