this is almost accurate but not
MTU is Maximum Transmission Unit including the Ethernet Encapsulation
The data size is determined by MSS or Maximum Segment Size
if you specify MTU 1500 and your application is sending 1500byte chunks of
Data then there will be fragmentation.
Today switches support MTU up to 1522 with no configuration required or as
we say out of the box.
look into the following to see what support what and how big :-)

You are correct that TCP/IP Illustrated Vol 1 - By W. Rachard Stevens is a
great book
