* new macro to remove magic number - IPV6_ADDR_SCOPES_COUNT; * sa6_checkzone() - this function checks sockaddr_in6 structure for correctness of sin6_scope_id. It also can fill correct value sometimes. * in6_getscopezone() - this function returns scope zone id for specified interface and scope. * in6_getlinkifnet() - this function returns struct ifnet for corresponding zone id of link-local scope.
