New Revision: 250041
URL: http://svnweb.freebsd.org/changeset/base/250041

Log:
  Debugging changes!
  
  * That lock isn't actually held during reset - just the whole TX/RX path
    is paused.  So, remove the assertion.
  
  * Log the TX queue status - how many hardware frames are active in the
    MAC and whether the queue is active.
