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.
