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.
