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.
