svn commit: r192708 - head/sys/dev/mii

[Pyun YongHyeon]

Author: yongari
Date: Mon May 25 01:41:05 2009
New Revision: 192708
URL: http://svn.freebsd.org/changeset/base/192708

Log:
  Use mii_phy_add_media() and remove usage of local macro ADD. Also
  checks extended status register to see whether the PHY is fast
  ethernet or not. This removes a lot of checks for specific PHY
  models and it makes easy to add more PHYs to e1000phy(4).
  
  While I'm here remove setting mii_anegticks as it is set with
  mii_phy_add_media().
