 *	Name:		ifconfig()
 *
 *	Description:	Configure the ethernet interfaces that are
 *			appropriate for the operation we doing, specified by
 *			ifconfig_type.
 *
 *              Note for SunOS MLS:
 *              Do not use the '-label' option to ifconfig here. The '-label'
 *              option will restrict the ethernet interface to a label range
 *              of system_low to system_low which is not acceptable for all
 *              uses by suninstall, dataless clients in particular.
 *  		A dataless  client mounts its /usr from the server and needs
 *		system_low to system_high access.
