Yes right, but the lookup principle is the same either you look at IPv6 flow label or you look at the Entropy label.
Correct, FAT, Entropy and IPv6 Flow Label are all in principle same, a way for source node to communicates what constitutes a flow. And in every case, there is no guarantee implementation has any performance gains, as implementation may choose to do normal flow speculation in addition of doing the fast thing.
That's right, and I didn't test that by sending forged packets (with conflicting L3+L4 keys and flow label) at the DUT to see if DUT uses L3+L4 keys or indeed relies on the flow information. adam
