svn commit: r229452 - stable/9/sys/dev/dc

New Revision: 229452
URL: http://svn.freebsd.org/changeset/base/229452

Log:
  MFC r227675:
    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.
