New Revision: 229454
URL: http://svn.freebsd.org/changeset/base/229454
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.
