Follow-up Comment #3, patch #6683 (project lwip):

The reason I change the seed to be an offset is to make sure we stay in the
given range for autoip. I admin there's an overbiasing of 0x100, but I don't
think the check is double: If the address given by
LWIP_AUTOIP_CREATE_SEED_ADDR is too high, the calculations below can fail to
get the address into the autoip range.

But I also can see it would be nice to just save the old address. While you
could just substract AUTOIP_RANGE_START from it in your implementation of
LWIP_AUTOIP_CREATE_SEED_ADDR, maybe I'll change it again. But I don't have the
time for that right now, I'm sorry.
