This patch series aims to improve datapath performance by reducing the amount
of flow key data hashed for each packet. The idea was Jesse's -- any bugs are
my own.

I've tested this on IPv4 and IPv6 flows with a WARN_ONCE() that caught some
cases of nonzero data past the presumed end of the flow key.
