svn commit: r217247 - head/sys/dev/re

[Pyun YongHyeon]

Author: yongari
Date: Mon Jan 10 23:47:11 2011
New Revision: 217247
URL: http://svn.freebsd.org/changeset/base/217247

Log:
  When driver is not running, do not send DUMP command to controller
  and just show old (cached) values. Controller will not respond to
  the command unless MAC is enabled so DUMP request for down
  interface caused request timeout.
