[Cake] fq_codel leveraging the skb->hash now in net-next

[Dave Taht]

It's not clear to me if all the encapsulation types (6rd for
example?), or drivers? are generating an skb->hash (or as of what
release of linux they did), and there's no error checking for 0, and
whether or not they are being permuted in skb->hash,  (otherwise all
linux implementations in the world will end up hashing the same way on
the same combination of ips and ports),

but I tend to trust eric to get it right, and hashing here was always
the 2nd or 3rd biggest hotspot in fq_codel.
