If we still want __refcnt being on cache line boundary, we might find a
better way to accomplish this.

Back to this issue again.

Eric, if you take a look at net-next right now, I left a dummy padding
in dst_entry where the neighbour pointer used to be.

Can you come up with some way to make use of that new space?

If route cache is removed, I believe we can remove all paddings.

Each tcp session will have its own dst_entry, instead of being shared.
