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

From: Hangbin Liu <[email-masked]>

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.

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()
