svn commit: r227675 - head/sys/dev/dc

[Pyun YongHyeon]

New Revision: 227675
URL: http://svn.freebsd.org/changeset/base/227675

Log:
  Partially revert r218788. r218788 removed calling dc_setcfg() for
  !DC_IS_ADMTEK in dc_miibus_statchg(). This change broke link
  establishment of Intel 21143 with dcphy(4) where it stuck in
  "ability detect" state without completing auto-negotiation.
  Also nuke dc_if_media as it's not actually used.
