[PATCH 2.5.74] convert appletalk/ipddp to dynamic allocation

[Stephen Hemminger <shemminger@xxxxxxxx>]

Part of the continuing campaign to fix all network devices to allocate 
dynamically.

Built, loaded/unloaded and configured but don't have real test environment to 
communicate
with other hosts.
