Subject: [PATCH v2 net 0/2] fix two kernel panics when disabled IPv6 on boot up

When disabled IPv6 on boot up, since there is no ipv6 route tables, we should
not call rt6_lookup. Fix them by checking if we have inet6_dev pointer on
netdevice.

v2: Fix idev reference leak, declarations and code mixing as Stefano,
    Eric pointed. Since we only want to check if idev exists and not
    reference it, use __in6_dev_get() insteand of in6_dev_get().

Hangbin Liu (2):
  geneve: should not call rt6_lookup() when ipv6 was disabled
  sit: check if IPv6 enabled before call ip6_err_gen_icmpv6_unreach()
