Cisco were asking customers what we'd like the 2nd core to do a couple
of months ago.

I can see how L2TP offload would help those that need it, but what I
was hoping for was a relatively basic split of functionality between
interrupt forwarding (ie CEF) on one CPU core, and anything else such
as control plane (good), slow-path (less good), etc on the other core.
This could be done simply, or presented as if it was dCEF and give us
rACLs/source-track/etc into the bargain.
