Yan, Zheng 7bd86cc282 ipv4: Cache local output routes ... Commit caacf05e5a causes big drop of UDP loop back performance. The cause of the regression is that we do not cache the local output routes. Each time we send a datagram from unconnected UDP socket, the kernel allocates a dst_entry and adds it to the rt_uncached_list. It creates lock contention on the rt_uncached_lock.
