It looks odd to save a source address in some struct named dst,
maybe it's the time to rename it.

It's an encapsulation struct for plain "struct dst_entry", which is a
path to a destination, or in other words a "route".  A "saddr" is a
valid key for a route.

I see no reason to change the name of this structure, it's perfect.
