svn commit: r244482 - head/sys/dev/mii

[Pyun YongHyeon]

Author: yongari
Date: Thu Dec 20 05:02:12 2012
New Revision: 244482
URL: http://svnweb.freebsd.org/changeset/base/244482

Log:
  Recognize 5720S PHY and treat it as 5708S PHY.
  Unfortunately 5720S uses 5709S PHY id so add a hack to detect 5720S
  PHY by checking parent device name.  5720S PHY does not support 2500SX.
