In this series I present next set of improvements/fixes: 1) If rtnl_talk(), called with answer != NULL fails it never returns with allocated answer: no need to initialize answer and free() it in the caller on error.
2) Correct ip6gre print endpoint address printing with ll_addr_n2a(): endpoints are IPv6 addresses, not hex dump. See individual patch description message for details.
