- * stolen from net-tools-1.59 and stripped down for busybox by
- *			Erik Andersen <andersen@codepoet.org>
- *
- * Heavily modified by Manuel Novoa III       Mar 12, 2001
- *
- * Pruned unused code using KEEP_UNUSED define.
- * Added print_bytes_scaled function to reduce code size.
- * Added some (potentially) missing defines.
- * Improved display support for -a and for a named interface.
- *
- * -----------------------------------------------------------
- *
- * ifconfig   This file contains an implementation of the command
- *              that either displays or sets the characteristics of
- *              one or more of the system's networking interfaces.

- *                     - gettext instead of catgets for i18n
