Link aggregation with round-robin policy cannot guarantee that packets
won't be reordered. Reordering is a *big* no-no for most ISPs, and is
the reason why LAGs are often used with hash-based packet distributions
which ensure that packets within one *flow* (for instance a single TCP
stream) won't be reordered.
