ipv4: Invalidate nexthop cache nh_saddr more correctly.
Any operation that: 1) Brings up an interface 2) Adds an IP address to an interface 3) Deletes an IP address from an interface can potentially invalidate the nh_saddr value, requiring it to be recomputed. Perform the recomputation lazily using a generation ID. Reported-by:Julian Anastasov <ja@ssi.bg> Signed-off-by:
