New Revision: 199916
URL: http://svn.freebsd.org/changeset/base/199916

Log:
  MFC 197590.
    Add hack to pass controller specific information to phy driver.
    Unlike most other PHYs there is no easy way to know which media
    type the PHY supports on Marvell PHYs. MIIF_HAVEFIBER flags is now
    passed via bus-specific instance variable of a device. While I'm
    here add 88E1112 specific work around to set SIGDET polarity low.
    Many thanks "Eugene Perevyazko <john <> dnepro dot net>" who kindly
    gave remote access to system with DGE-560SX.
