I realize you have been directed here but this is not the right place to 
discuss TCK exclusion requests.

 From the mails you forwarded then it looks like there are issues with 
the multicast support in your port to NonStop. The IP_MULTICAST_ALL 
socket option you mention is used in the Linux port to avoid 
interference when two sockets are bound to the same port but joined to 
different multicast groups. Linux is an outlier in this scenario so the 
socket option is set to prevent the interference. My guess is that few 
people here will know NonStop but you could being porting questions on 
this code to net-dev.
