around and translates to sw_flows and in turn into ndo_swdev_flow_* calls.
And herein lies the fundamental disagreement.
I dont believe the flow interface is appropriate for either L2/3.
We already have some L2 interfaces (they are incomplete if you want
to capture everything a large switch does).
L3 should go the same path.
And as i said earlier, i dont think the flow interface
is appropriate as a universal classifier interface either.
You need to allow for different types of classifiers. You
need to allow for a mix and match of classifiers (although
the later could be evolutionary).
