svn commit: r186389 - head/sys/dev/re

[Pyun YongHyeon]

New Revision: 186389
URL: http://svn.freebsd.org/changeset/base/186389

Log:
  Since we don't request reset for rlphy(4), the link state 'UP'
  event from mii(4) may not be delivered if valid link was already
  established. To address the issue, check current link state after
  driving MII_TICK. This should fix a regression introduced in
  r185753 on fast ethernet controllers.
