o break per-address family support out into separate files o modularize per-address family and functional operations using a registration mechanism; this permits configuration according to which files you include (but beware that order of the files is important to insure backwards compatibility) o many cleanups to eliminate incestuous behaviour, global variables, and poor coding practices (still much more to fix) The original motivation of this work was to support dynamic addition of functionality based on the interface so we can eliminate the various little control programs and so that vendors can distribute ifconfig plugins that support their in-kernel code. That work is still to be completed. o Update 802.11 support for all the new net80211 functionality; some of these operations (e.g. list *) may be better suited in a different program
