Ok, here's verbose dump below. Down sequence is executed in the same order as up, although should be in reverse. And to check whether list of remaining interface definitions is empty for any given interface to avoid setting link down. That way dhcp6 will be released first, then dhcp4 release and finally wpa termination and link down. Don't know if anyone can produce a patch for that nw source file though %(
