     Now we have the following code here:

   ifr->ifr_ifru.ifru_icmp6stat =
           *((struct in6_ifextra *)ifp->if_afdata[AF_INET6])->icmp6_ifstat;

I don't understand what's the point of bzero()'ing this object (struct 
in6_ifextra, as I see) just before assignment? Doesn't the second statement
overwrite _all significant_ result of the first one?
