Two errors have been spotted, when IPv6 is enabled in the ravenusb
Project-Makefile:
#CONTIKI_NO_NET=1
CONTIKI_WITH_IPV6=1
The compile error results from a variable name mismatch in cdc_task.c
The variable 'r' is undeclared and should be renamed to 'route'
The linker also fails with 'undefined references'
This has been mediated by adding 'core/net' to Modules in the
Project-Makefile.
