Author: jilles Date: Sat May 14 12:22:58 2011 New Revision: 221884 URL: http://svn.freebsd.org/changeset/base/221884 Log: network.subr: Use printf(1) builtin for hexprint function. Now that printf(1) is a shell builtin, there is no need to emulate it anymore. The external printf(1) is /usr/bin/printf and therefore may not be available in early boot. It may be faster to use printf directly but the function is useful for compatibility.
