Count and display outer IP checksum errors in the checksum
forwarder.

Example forwarder stats output:
  RX-packets: 158            RX-dropped: 0             RX-total: 158
  Bad-ipcsum: 48             Bad-l4csum: 48            Bad-outer-l4csum: 6
  Bad-outer-ipcsum: 40
  TX-packets: 0              TX-dropped: 0             TX-total: 0
