svn commit: r246648 - head/sys/dev/ath

[Adrian Chadd]

Author: adrian
Date: Mon Feb 11 02:48:49 2013
New Revision: 246648
URL: http://svnweb.freebsd.org/changeset/base/246648

Log:
  Extend the timestamp to be a timeval, rather than ticks.
  
  This makes it easier to see TX and RX buffer latencies.
