Icmp packets with wrong checksum are never dropped since skb->ip_summed is
set to CHECKSUM_UNNECESSARY.
When icmp packets with wrong checksum pass through the octeon net driver,
the not_IP, IP_exc, L4_error hardware indicators show no error. so the
driver sets CHECKSUM_UNNECESSARY on skb->ip_summed.
L4_error only works for TCP/UDP, not for ICMP.

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.

The octeon-ethernet driver supports the sgmii, rgmii, spi, and xaui
ports present on the Cavium OCTEON family of SOCs. These SOCs are
multi-core mips64 processors with existing support over in arch/mips.
The driver files can be categorized into three basic groups:
1) Register definitions, these are named cvmx-*-defs.h
2) Main driver code, these have names that don't start cvmx-.
3) Interface specific functions and other utility code, names starting
with cvmx-
