Staging: Octeon Ethernet: Convert to NAPI.
Convert the driver to be a reasonably well behaved NAPI citizen.
There is one NAPI instance per CPU shared between all input ports. As
receive backlog increases, NAPI is scheduled on additional CPUs.
Receive buffer refill code factored out so it can also be called from
the periodic timer. This is needed to recover from temporary buffer
starvation conditions.
