ip6_dst_lookup - perform route lookup on flow : socket which provides route info : pointer to dst_entry * for result : flow to lookup

This function performs a route lookup on the given flow.

It returns zero on success, or a standard errno code on error.

ip6_sk_dst_lookup_flow - perform socket cached route lookup on flow : socket which provides the dst cache and route info : flow to lookup : final destination address for ipsec lookup : we are in a sleepable context

This function performs a route lookup on the given flow with the possibility of using the cached route in the socket if it is valid. It will take the socket dst lock when operating on the dst cache. As a result, this function can only be used in process context.

It returns a valid dst pointer on success, or a pointer encoded error code.
