Generally we only log real errors. Is a receive buffer overflow a real
error? I would say not. But it would be good to count it.

There was also the open question, what exactly does a receive buffer
overflow mean?

The spec says:

  9.2.8.11 RXBOE

  Receive Buffer Overflow Error. When set, this bit indicates that the
  receive buffer (from the network) has overflowed and receive frame
  data was lost.

Which is a bit ambiguous. I would hope it means the receiver has
dropped the packet. It will not be passed to the host. But other than
maybe count it, i don't think there is anything to do. But Ramón was
suggesting you actually drop the frame currently be transferred over
the SPI bus?
