The datasheet 8.19.29 "Good Packets Transmitted Count - GPTC (0x04080;
RC)" says:
> This register counts the number of good (no errors) packets
> transmitted. A good transmit packet is considered one that is 64 or
> more bytes in length (from <Destination Address> through <CRC>,
> inclusively) in length.
It also says similar for the other Tx statistics registers. Add the
number of bytes for CRC to those registers.
