	This patch is all implemented within the ifenslave user space
program, which, to my knowledge, is not currently used by any major
distro to configure bonding.

	The configuration for bonding is typically performed by packages
such as initscripts or sysconfig, and this functionality would likely
need to go there.

	The only real use for ifenslave.c is on kernels without sysfs
compiled in.
