[Adrian Chadd]

Author: adrian

New Revision: 242508
URL: http://svn.freebsd.org/changeset/base/242508

Log:
  Add a debug method to dump the EDMA TX status descriptor contents out.
  
  This requires some HAL API changes to be useful, as there's no way
  right now to pull out the TX status descriptor contents.
