This is to add an ip_dev_find like function for ipv6, used to find
the dev by saddr.
It will be used by TIPC protocol. So also export it.

Without ub->ifindex set for ipv6 address in tipc_udp_enable(),
ipv6_sock_mc_join() may make the wrong dev join the multicast
address in enable_mcast(). This causes that tipc links would
never be created.
So fix it by getting the right netdev and setting ub->ifindex,
as it does for ipv4 address.
Patch 1 is to add a function to get the dev by source address,
whcih will be used by Patch 2.
Xin Long (2):
ipv6: add ipv6_dev_find()
tipc: set ub->ifindex for local ipv6 address
