[PATCH iproute2 0/2] ip/tunnel: Do not free() answer on rtnl_talk() error, correct ip6gre

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.

Thanks,
Serhii
