I mostly agree with Jamal.  As far as the concept of a policy
lookup cache goes (which appears to be at the core of OVS), this
almost fits exactly onto a u32 hash table.  All that would be needed
is to add the tail end of the policies, e.g., with new packet
actions.

However, this is purely based on my conceptual view of OVS, which
may or may not be accurate.  I'll dig into the patches over the
next couple of days to see if they could be easily turned into
packet actions or whether this is difficult for reasons that we
have not yet discovered.

Cheers,
