CAN can do up to 1Mbit/second, but the NMEA 2000 implementation specifies
a slower speed.  This is because NMEA 2000 has to work with a maximum
length CAN bus the same length as an oil tanker or aircraft carrier.  The
low level CAN protocol requires that the maximum round trip delay be a
fraction of a bit time.
