Author: attilio Date: Fri Aug 6 20:50:48 2010 New Revision: 210966 URL: http://svn.freebsd.org/changeset/base/210966 Log: Some network functions replicate the behaviour of some network stack functions because they can't trust them. In order to stress out the dependency, improve the relative comments.
