It would definitely help if you could expose some more details on the
"some network processor" you have. We're all very eager ;-)

Well, this thing doesnt run ovs ;-> (/me runs). If you come
to netdev i may let you play with it ;-> Its a humongous device
(think multi 100G ports).

On a serious note: Even if you took what Simon/Netronome has
(yes, I know they use ovs;->) - there is really no need for a switch
abstraction *at all* if all you want to is hang a packet
processing graph that ingresses at a port and egress at another port.
As you know, Linux supports it just fine with tc.

You have a pointer to the kernel driver for that HW?  Can you show how
you're using Linux tc netlink msg in kernel to program HW?  I'd like
to see the in-kernel API.
