[ECOS] global addressing in ecos

We've applied the patch and re-run all the tests for the stateless address 
autoconfiguration, and we also exempted the tests indicated below (21-30, 
54-56). The tests that passed are those that wait for the DAD to fail (it 
wants the target to basically not send any echo reply/packet) and all the 
other tests failed. These are basically the tests that wants the target to 
echo-reply. We believe that the cause is that the global address cannot be 
set; it would seem that the target does not respond to DAD which are sent 
using a multicast address.

This seems to lead me into thinking that the entire set of stateless 
autoconfiguration is exempted. Can anyone please verify? Or on another train 
of thought, I would like to ask if anyone would know why we cannot set the 
global address, and why the target does not seem to respond to multicast 

I would like to ask Mr. Hamilton if you could share your test results for 
the ecos target tested by TAHI if this is not confidential so we could more 
or less compare our test results with yours.

Thank you.
