Author: adrian Date: Sat Nov 3 04:53:44 2012 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.
