Good point! But I think we'd be moving in the right direction.
tx_bytes should count bytes sent to the network, not data+metadata
sent on an internal bus.

If you connect this board to a different controller directly the
rx_bytes of the other end should match the tx_bytes of the board 
with mse102x. The byte accounting would benefit from further massaging
in a separate patch.
