Author: adrian Date: Fri Sep 16 06:33:12 2011 New Revision: 225607 URL: http://svn.freebsd.org/changeset/base/225607 Log: Tidy up the CAB queue defaults; do the same for AR5212. * add a check to the AR5416 CABQ setup to ensure a minimum cabq time; that way a negative calculated cabq time doesn't annoy things; * Port the AR5416 CABQ setup stuff to AR5212. TODO: still do this in the driver..
