Author: andre Date: Sun Oct 20 18:13:06 2013 New Revision: 256797 URL: http://svnweb.freebsd.org/changeset/base/256797 Log: Sorta fix the wb(4) driver to allocate complete mbuf+cluster packets and remove the need for MEXTADD. I don't believe the driver was in working condition before. Untested due to lack of hardware.
