I was somehow under the impression there was a larger maximum size, too.

At 1Gb/sec, switching or routing millions of 1.5K frames just to transfer
one large file seems particularly idiotic.  Even most 100Mb/sec Ethernet
cards can be configured to use FDDI-sized (4k) frames, though not all
(few?) switches can cope with this...
