Bits of saddr saved in spi field are supposed to be just hashing helper,
allowing to avoid hashing all the tunnels of all the tunnels ending
at our host and, hence, having one destination address, at one hash bucket.
IPv6 should do full check for saddr and can use some folded hash value
of saddr as spi.
